Since the rpms of the motor are constantly rising, there couldn't be a harmonic motion for more than a split second. The only reason the tower is stable is because it's standing on marbles, which let the tower roll free in the oversized shaking base. Clever solution surely. But no harmonic motion is taking place here.
Hello guys. I'm an earthquake engineer. This is a little different from a real earthquake simulation because earthquake moves the buildings in 3 directions but this table only moves in 1 direction. Also earthquakes have many different frequencies happening randomly not increasing gradually. The third difference is seismic isolators must have a returning mechanism that means after the building is moved, it tries to bring it back to its original location. The four marbles used couldn't bring the building back to center and it caused the shake table hitting the foundation. Anyways it was really fun to watch. Thank you 😊
I once had an idea about a wind mill that didn't use the wind Pressure vibrations when I realized that. A buildings foot print hydraulic centered in xyz as for the vibrations they are absorbed by a cushion that turns vibrations to elastic When we say earth quake we say rapid Omnidirectional displacement distance traveled energy over time. Which means you move the way the quake moves you instantly

@@uggsxx9155 To be fair, both of you are right and wrong.

You can watch online how it saved Taipei 101 from a collapse a day ago when an earthquake of 7.4 magnitude struck taiwan...
@@hugostiglitz491 ya such a cool project, we did something kind of like that. Had to make a small car and send them down a ramp to see who's goes farthest and straightest.
So much better to see this rather than teachers handing out packets non stop. In my class we had to build a bridge and it would be tested with a certain amount of wait. Tons of fun and a positive learning environment.
We actually did this it was a challenge just with different requirement, 50 g’s weight limit, 20in, 10x10 base, had to hold 500g (x10 weight), and survive a rigged shake test that was different time for everyone. Only materials where a base cardboard and top cardboard that where included in the weight, hot glue, and only 20 raw spaghetti
@@levone8958 We also did a bridge from popsicle sticks when I was younger. It's one of the only things that I still remember from middle school. Hands on projects should be the norm in schools.
To save money, the shaking device and expert would travel the area, teaching a different school each week, while the normal teachers teach how it all works using books and chalk boards like in the old days . Each school knows what week the children will need to have their stick models and basic knowledge ready .
We did something like this at my school where they were statically tested with weights. Probably a little cheaper to run, though you still have to buy the wood.
To be fair, your school probably had the budget. Your teacher just said “not my job”. You might not have the budget to buy a pre-made one, but a motor is like $5 and the woodworking class has the materials to make one. It’s not rocket science, between your science teacher and shop teacher they’d have known how to make one for $5 and some change.
This is why I loved my physics teacher. It felt like I was learning real things that affected me every day + getting to apply what we learn actively. Love that class.
The look on the kids faces tells you the importance of good teachers and programs, to get them interested in exciting career fields and keep them on the right tracks.
I dont know how old you guys are, we do this in school a few years ago. And to be honest, i wished there were more students like them who are actually interested. Because if you think this is fun, there will always be someone who is bored and probably will comment on youtube in the future about how bored they were at school even though it was fun to others like me.

Teaching the future generations how to function in soceity after the older generations are retired or dead is a very important job.
The marbles under the structure mimicked a "base isolation" seismic system. The structure is isolated from a lot of the ground motion. Super effective and typically used for critical structures like hospitals or high rise buildings. Cool model!
@@tristintaylor7999 Not in this case. Since the machine only shakes in one direction, you theoretically only need bracing parallel to the shaking to resist those forces (which it has on both walls for the full height of the structure) If you look closely, the structure failed at the base connection of the rightmost column. The braced frame along the height of the structure remained intact as it toppled over. So it did it’s job.
That movement that finally dropped it down was probably a magnitude 9+ earthquake comparable, since it took way too much movement. That means they built that building pretty good.
At the point near the end they were say 15 seconds before it dropped. You Xanax here then say ttat. It could have gotten as close. As close as 18. How devastating that would be anywhere, especially in a big city
I mean it seems like a fun project tbh. Like I know I would've absolutely LOVED this kind of lesson. Not only does it teach but also provides entertainment at the same time. Which makes kids focus more on the lesson as they're genuinely interested in it
Yeah.... I'm fairly sure the base has room to move around in, so the tower is just staying in the middle because of the friction keeping it centered. I say this because it makes sporadic movements and loud snaps when the tower does hit the plate Edit: seeing the marbles makes me think this was the plan all along, and everybody probably had the same opportunity to use a similar solution. So while the test is a little flawed, it is the same for everybody However, there are definitely no harmonics going on. This would happen at a certain rpm of the shaker motor and only be stable at that setting. Since the vibration speed is constantly rising, there can't be a stable state for more than a split second. And the tower is clearly stable throughout a large range of the rpms.
@@ThomasKent1346 Nope. Mechanical resonance is where the different movements line up due to the frequency and amplify these movements. Usually leading to failure. The phenomenon in this experiment would be called harmonic frequency. Where the movements cancel each other out. But that's also not exactly what is happening. The tower is loose in the base and rolling on marbles. There is barely any force transfered to the tower because it can freely roll. Technically the friction of the marbles have a achieved a stable state which can be described as harmonic, since they are moving themselves left and right at the same rate as the vibrating platform. Causing the tower to remain in place. Until at one point, the tower is moving in 1 direction fast enough to collide with the return stroke of the shaking base. Causing a large shock which breaks the tower.
You mean when the structure lost contact with the mechanism..? Cuz it wasn’t being touched by either side and was instead perfectly sliding without contact.
I worked for a company that makes earthquake proof houses in Japan. These students got the concept of what I learned from the blueprints. Great job teacher! 👍🏻
Wait so it's true? My hubby went to Japan and he sent me some pics of the bridges how they where on like swivels or something? How or what are those? He asked and they just said earthquake but how are they more resistant if you don't mind explaining
For everyone wondering why it stopped moving, it's called antiresonance. Soon after, it started shaking hard and broke, this is called a resonance. The values of antiresonances and resonances can be calculated before building the building and you have to consider them when designing the skyscrapers etc.
I remember being on the couch for my one and only earthquake, happened when I was a kid. The couch just slid from the middle suddenly to slam into one wall, then the other, then back to the first. Honestly remember it being kinda fun cause I was too young to really know the danger
And in the 10,000 aftershocks it can roll from other directions or just shake. After a while anything under a 5 doesn't really register but anything above you get amazingly good at predicting it's strength. Then you think you're over it and you're sitting on a sofa and someone walks behind it... cue freakout from the vibrations.
@@CJ-im2uu that's why idk why these engineeres thought that earthquake moves side to side. Looks like most of them didn't experience the real deal earthquake
Yup, was eating a meal with a neighbor and my mom on Easter Sunday a few years back. Felt like I was on a damn boat, but we were sitting at the table, in a house, on a concrete slab. In certain areas and at high magnitudes, the ground actually "liquefies" and behaves like a fluid, with soil and vegetation rippling up and down like choppy waves on the ocean. Earthquakes are no joke, it's a massive amount of energy and stress being released.
The frequency is probably scaled to allow for there being no scalable mass in the tiny building frame. You can't replicate the effect of real life size mass and inertia in a small scale.
Small men become elementary school teachers because they failed to achieve higher endeavors. No right minded man wants to hang out with children for their entire career.
Best design Ive seen. The building actually got more stable as the shaking continues until it reached the breaking point and it happened on the foundation not because it was top heavy. Very impressive
It was just a clever use of marbles, the foundation was placed on top of them, so that it would roll back and forth and remain stable instead of shaking.
@@willhenry3011 Nah they aren’t just ball bearings lmao. They are giant balls made of steel or concrete. They weighs anywhere from 300 to 800 tons which just a lil bigger than most ball bearings. And they are usually suspended in the building using springs and pistons. It’s not like the marbles shown in the video, like the original comment said they are counterweights. They are in the top of skyscrapers and sway in the opposite direction of forces to negate them and prevent resonance, reduce motion sickness, and counter storm winds.
Very smart design. Weight in the middle for stability so it doesn't shift a lot. A more stable design for the poles couldve been made but its still very nice.
@@Hello_there_obi or maybe, just maybe it was an experiment demonstrating the effectiveness of inertial dampening. But no they are definitely stupid and none of this was for any point except to show bad building technique. Marbles as a stand-in for rollers or an inertial dampening system at the base of a building would be a pretty cheap and effective way to show the effectiveness of such systems to a group of young students I would think. But I am no Matt Bolt, King of blu tac.
There are many things I find pleasing here.. the engineering, the context, the lack of understanding in the room that makes me giggle... But the best part to me is the teacher we don't see or hear, not only getting the youth interested and excited about it, but letting this generation express their interest and excitement freely because it's about the subject. That's precious to me. ❤️
Oh I love when teachers find a way like this to not only get students interested in a subject or an assignment, but to also help with understanding an idea or theory. And what a good conversation it brought about. Amazing job to everyone.
Yeah, I love teachers who love to teach and help their students understand things in fun ways. I don't think I ever had one like that. The ones I had were there for the paycheck.
I absolutely agree. This is why teachers deserve to be paid so much more money than what they make now. God Bless all teachers especially those who really love there jobs and love educating our youth!!!
Made that in high school in the early 90’s. Mine survived the earthquake and the weight test with flying colors. The teacher came back over with a wood Malloy and bash the hell out of it and said “well looks like it didn’t survive the nuke test!” He was a cool teacher!
@AL-xx2dw resonant frequency is where the movement of the table is going through the structure, bouncing off the top and coming back. The frequencies overlap and either build on top of eachother or subtract from eachother in what is called either constructive or destructive superposition. As the frequency or speed of the table increases the system goes from constructive to destructive and back. When the system is in constructive superposition the force of the waves traveling through it it doubled so the structure falls. This is the reason soldiers can't march over bridges or they will fall
I was taking bout the frequency of the object that matched the frequency of the earthquake which is why the structure seemed to stop moving at one point.
@@oscarhughes5532 bro wtf, you explained resonance frequency when the "what" comment was referring to the fact that why tf else would they be doing this experiment if thats NOT what they were learning in class
@@JustinWayneDawgThis is common braced framing? Hes just saying its built well and lists his credibility as someone who regulary contructs these structures at full scale.
Only reason that broke is because of the weakness of the material, but for most tests, this machine and it’s relative machines are great for measuring up someone’s building skills.
I really don't miss much about highschool but one thing I do miss is these types of demonstrations and such that everyone would gather around the teachers desk to watch.
sadly, most teachers are miserable af (bad pay and terrible students) so by the time u get to high school, they dont give a fuck abt making learning fun
Took general physics just because we did more hands-on stuff vs. Writing/textbook reading like in advanced physics. The advanced class was always jealous of the general class since we had more fun. We did catapults, mouse trap race cars, spaghetti bridges while they got writers cramps lol
That's like when my science class did crash test cars, and I built mine with a rear-facing back seat. From passengers did mediocre, rear passengers had the best score in the class.
You guys must have went to some schools with funding, I went to a predominantly black school and we rarely ever did physical experiments, it was always on some bullshit website with simulations, even then we never did this one. They never taught us anything of meaning
yes, I watch old japanese TV show (about old home renovation) and many of their house built with that diagonal struts in the walls. That struts the main core how the building stabilize during earthquake. the simple one is using a huge diagonal beam from a corner to corner, but if the house located on more prone to had earthquake, then the other corner will add simillar mini beam on the untouch corner, and they put is rubber cushioning in the corner, act like shock absorber & help maintain pendulum effect to stabilize the whole building. taller building (taller than 3 floors) they will put a real rubber shock absorber & some cushoning under each pillar, allow the building wobble steadily along with earthquake frequency. the key for enginering (i think) to this problem is to understand how not only neutralize the wobble, but also how allow the building move along to mitigate the earthquake vibration. Japan Tohoku Eartquake (that cause Nuclear Powerplant exploded) is considered scary, as the land not only move side to side, but also ups & down in all directions, which very damaging, especially if the building not cushion properly.
This was incredible to watch from a dad’s view and just from my own general knowledge.Excellent job guys, that structure would’ve kept on holding on if it wasn’t for the base slipping from underneath but that’s what learning is about! Keep up the excellent work guys 💪🏽

This student actually took time to learn what causes the buildings to break down. But ensuring that it's not completely solid at the base, they've ensuring it's flexibility allowing the model to endure near the end.
Nice! Reminds me of my first engineering class in college, we were divided into groups and we each had a major project for the end of the year...build a concrete canoe, any that floated went to the next round where we started loading people in and any that held a couple people would race to see which could not only float but which was the most hydrodynamic
I remember we had to build a boat that could both float and go under a bridge without destroying the bridge and one team made a boat so tall that it squuuuuuueaked under that bridge so close it took minutes. Not a soul breathed the whole time, I remember the jubilation when they cleared it. Wasn’t even my team, it was just so tense
I laughed so hard because the kid in the back looked away at the exact moment it fell off 😅 he quickly looked back when hearing the noise like shit... I missed it!
Ive had the fortune to build skyscrapers for a living. Seeing this was cool. Watching buildings 40 stories tall sway 10-20 feet in either direction is pretty wild as well
I remember winning the race we had after we made our own design and filling it up with pennies and putting them on the water to see how many would sink it mine didn't sink and had the most pennies in it pretty neat remembering that cause not really any other fun games like that to learn when I was in a hook sadly I would've liked school more
We had a principal of technology class in my school that was super fun we made cardboard boats and then took them into the pool to see whose boat would last the longest we also made Rat Racers using Rat Traps
I did that I school too I won that competition too mostly because I had been studying boats and how they float for a long time we got 33 pennies in before it sank the only reason it did was because of the weight made the water go over the sides

Every Friday he passed out 1 page with 10 or so questions on it.. multiple choice and the Page#/Paragraph# where the answer was... took a whole 3-4 minutes to do it. Rest of the page was filled with his "pig portraits" that he drew of us... every week he pick couple students for the portraits lol. THAT was the ONLY time we opened our books each week.

We would get stories from his time there.... like if someone dies you basically stopped what you doing and have the funeral that day if possible or next morning because the smaller villiges did not have electricity or refigeration or even a morge... sothey have to get them in the ground quick. He had a parrot that was like 12-13 yrs old and for some reason.. one day it decided to HATE me and would do whatever it had to do to bite me... When he clipped the wings I thought I would get a break... but NOPE! That ASSHOLE would inch his way down his perch, walk to edge of counter, inch is way down the counter and drawers, waddle across the floor, climb up my damn leg... non agressive but matter of factly (thoght he might have got over it or something cuz it was just climbing and not attacking... till it got on my shoulder justr to BITE my damn EAR!! lol One day I forgot my glasses and NOTHING... was like I was a stranger.. we both noticed that and figured it was someone with glasses that did something to it... so I didn't wear them for bout a week and then the damn thing caught on and back to business as usual...

Also earthquakes have many different frequencies happening randomly not increasing gradually.

No, and that's why it works so well
It would have collapsed faster if it had the walls coverings as it would become very unstable the moment a wall panel would face shifted the weight

Its because of those glass marbles under the building. This thing is known as base isolation. And it keeps the building safe from seismic excitations.
Glass marbles under the building? To keep safe from an earthquake???? Who'd a thunk it!
@@Scott-po6go he scott hope you are doing good.
Actually for this small project they have used glass marbles to isolate the building from the foundation. For large scale building friction pendulum bearings (metal balls) or rubber bearings are used for isolation. Some buildings like Taipei 101 in taiwan used tuned mass dampers on top of the building to resist seismic excitations. You can watch online how it saved Taipei 101 from a collapse a day ago when an earthquake of 7.4 magnitude struck taiwan...

So much better to see this rather than teachers handing out packets non stop. In my class we had to build a bridge and it would be tested with a certain amount of wait. Tons of fun and a positive learning environment.

To save money, the shaking device and expert would travel the area, teaching a different school each week, while the normal teachers teach how it all works using books and chalk boards like in the old days . Each school knows what week the children will need to have their stick models and basic knowledge ready .
@@Taipanslol, difference between public and private
We did something like this at my school where they were statically tested with weights. Probably a little cheaper to run, though you still have to buy the wood.
To be fair, your school probably had the budget. Your teacher just said “not my job”. You might not have the budget to buy a pre-made one, but a motor is like $5 and the woodworking class has the materials to make one. It’s not rocket science, between your science teacher and shop teacher they’d have known how to make one for $5 and some change.
This was one of my favorite classes in school. They called it problem-solving and you would get up in little groups and do stuff like this.
This is why I loved my physics teacher. It felt like I was learning real things that affected me every day + getting to apply what we learn actively. Love that class.

It's all about practical applications. One major thing I wish all teachers did.
We did bridges. One kid made one so strong it held our teachers full weight. I'll always remember that lesson
I still have my balsa wood bridge! It held the max weight. My design was simple yet effective X bracing to hold the structure together. 23 years ago!
Outta what?! 😮
@@Andrea-LovesYouStill for some reason, I want to assume balsa wood
It held All dat ass?
I made a bridge that could hold my weight (60 kg) first year of highschool with only using paper
I remember building these in 7th grade, And Co2 cars. The glory days.
The marbles under the structure mimicked a "base isolation" seismic system. The structure is isolated from a lot of the ground motion. Super effective and typically used for critical structures like hospitals or high rise buildings. Cool model!
Would it have benefited more from having the cross frame on all four sides instead of just two?
@@tristintaylor7999 Not in this case. Since the machine only shakes in one direction, you theoretically only need bracing parallel to the shaking to resist those forces (which it has on both walls for the full height of the structure)
If you look closely, the structure failed at the base connection of the rightmost column. The braced frame along the height of the structure remained intact as it toppled over. So it did it’s job.
In California this is basically required for svery building by law
In the case of a real structure, what would be used in place of the marbles?
@@fullmetal7984 not sure about america, but buildings in New Zealand have these huge pads made of rubber that buildings sit on. Pretty mental tbh
That movement that finally dropped it down was probably a magnitude 9+ earthquake comparable, since it took way too much movement. That means they built that building pretty good.
Yup, we can't escape God smite... That's already good for people to escape from building while it collapse

The moment it went still is the exact moment the vibrations synchronized with the structure’s framework
Yeah.... I'm fairly sure the base has room to move around in, so the tower is just staying in the middle because of the friction keeping it centered.
I say this because it makes sporadic movements and loud snaps when the tower does hit the plate
Edit: seeing the marbles makes me think this was the plan all along, and everybody probably had the same opportunity to use a similar solution. So while the test is a little flawed, it is the same for everybody
However, there are definitely no harmonics going on. This would happen at a certain rpm of the shaker motor and only be stable at that setting. Since the vibration speed is constantly rising, there can't be a stable state for more than a split second. And the tower is clearly stable throughout a large range of the rpms.
Resonant frequency.
@@ThomasKent1346 Nope. Mechanical resonance is where the different movements line up due to the frequency and amplify these movements. Usually leading to failure. The phenomenon in this experiment would be called harmonic frequency. Where the movements cancel each other out.
But that's also not exactly what is happening. The tower is loose in the base and rolling on marbles. There is barely any force transfered to the tower because it can freely roll.
Technically the friction of the marbles have a achieved a stable state which can be described as harmonic, since they are moving themselves left and right at the same rate as the vibrating platform. Causing the tower to remain in place.
Until at one point, the tower is moving in 1 direction fast enough to collide with the return stroke of the shaking base. Causing a large shock which breaks the tower.
@@ThomasKent1346looks like somebody watched to much MatPat
You mean when the structure lost contact with the mechanism..? Cuz it wasn’t being touched by either side and was instead perfectly sliding without contact.
It's nice to see young people learning and doing meaningful things like this
I worked for a company that makes earthquake proof houses in Japan. These students got the concept of what I learned from the blueprints. Great job teacher! 👍🏻
Wait so it's true? My hubby went to Japan and he sent me some pics of the bridges how they where on like swivels or something? How or what are those? He asked and they just said earthquake but how are they more resistant if you don't mind explaining
So... Marbles as footings? Got it.
Am I correct in thinking that in Japan, when they build skyscrapers. They put huge springs in the foundations??
You put ball bearings under the buildings?
You guys put balls in your buildings in japans foundation?
For everyone wondering why it stopped moving, it's called antiresonance. Soon after, it started shaking hard and broke, this is called a resonance. The values of antiresonances and resonances can be calculated before building the building and you have to consider them when designing the skyscrapers etc.
no its becasue its sitting on marbles ie taking out 90%of any movement. when it speeds up its just engaging the marbles to take out near 100%

I remember being on the couch for my one and only earthquake, happened when I was a kid. The couch just slid from the middle suddenly to slam into one wall, then the other, then back to the first. Honestly remember it being kinda fun cause I was too young to really know the danger
And in the 10,000 aftershocks it can roll from other directions or just shake. After a while anything under a 5 doesn't really register but anything above you get amazingly good at predicting it's strength. Then you think you're over it and you're sitting on a sofa and someone walks behind it... cue freakout from the vibrations.
I was in the Loma Prieta. There were times when it felt up and down and side to side.
@@CJ-im2uu that's why idk why these engineeres thought that earthquake moves side to side. Looks like most of them didn't experience the real deal earthquake
Yup, was eating a meal with a neighbor and my mom on Easter Sunday a few years back. Felt like I was on a damn boat, but we were sitting at the table, in a house, on a concrete slab.
In certain areas and at high magnitudes, the ground actually "liquefies" and behaves like a fluid, with soil and vegetation rippling up and down like choppy waves on the ocean. Earthquakes are no joke, it's a massive amount of energy and stress being released.

It was just a clever use of marbles, the foundation was placed on top of them, so that it would roll back and forth and remain stable instead of shaking.
This is why tall buildings in earthquake zones have mechanical counter weights, preventing the resonant frequency from tearing itself apart.
@@willhenry3011 Nah they aren’t just ball bearings lmao. They are giant balls made of steel or concrete. They weighs anywhere from 300 to 800 tons which just a lil bigger than most ball bearings. And they are usually suspended in the building using springs and pistons. It’s not like the marbles shown in the video, like the original comment said they are counterweights. They are in the top of skyscrapers and sway in the opposite direction of forces to negate them and prevent resonance, reduce motion sickness, and counter storm winds.

These kids got a lesson in frequency and their teacher didn't even know.
......what
@AL-xx2dw resonant frequency is where the movement of the table is going through the structure, bouncing off the top and coming back. The frequencies overlap and either build on top of eachother or subtract from eachother in what is called either constructive or destructive superposition. As the frequency or speed of the table increases the system goes from constructive to destructive and back. When the system is in constructive superposition the force of the waves traveling through it it doubled so the structure falls. This is the reason soldiers can't march over bridges or they will fall
I was taking bout the frequency of the object that matched the frequency of the earthquake which is why the structure seemed to stop moving at one point.

Houses in Japan are built much like that model where the foundation is made to glide back and forth and the frame wobbles along.
Got to with how it is in Japan
every modern sky scraper
Old news bro
yes, I watch old japanese TV show (about old home renovation) and many of their house built with that diagonal struts in the walls. That struts the main core how the building stabilize during earthquake. the simple one is using a huge diagonal beam from a corner to corner, but if the house located on more prone to had earthquake, then the other corner will add simillar mini beam on the untouch corner, and they put is rubber cushioning in the corner, act like shock absorber & help maintain pendulum effect to stabilize the whole building.
taller building (taller than 3 floors) they will put a real rubber shock absorber & some cushoning under each pillar, allow the building wobble steadily along with earthquake frequency. the key for enginering (i think) to this problem is to understand how not only neutralize the wobble, but also how allow the building move along to mitigate the earthquake vibration. Japan Tohoku Eartquake (that cause Nuclear Powerplant exploded) is considered scary, as the land not only move side to side, but also ups & down in all directions, which very damaging, especially if the building not cushion properly.

-Loki
@@kekw35 Ironically, Loki and Thor are not brothers. However, Thor did have 3 brothers, but their names are Baldr, Vidarr and Vali. Vidarr is destined to avenge his father and kill Fenrir, who in turn has 2 brothers and 1 sister (Sleipnir, Jörmungandr and Hel, though Loki was actually the mother of Sleipnir so not sure if that counts). Vidarr will also survive Ragnarök
I remember this in HS. My tower was one of 2 that survived the tests, so the teacher wouldn't let me keep it. He wanted to use the sucessful towers to teach the students next year. (It was the first year the course was offered.)
that's sad doe
Big oof but that's something to be proud of.
@@Uniformtree000 My art teacher in HS kept 75% of my pieces because she was in her first year aswell. I have no idea if she still has them or not.
that’s pretty cool though because they’re just gonna keep using yours for ever. my teacher uses examples from her old students and she says some of the stuff is like 16 years old
Nice! Be proud of yourself! I once built a volcano model with full function in 8th grade with island, water and all that and its still there as a memorial of my genius brain.
Future engineers right there, and it makes me happy that they are so happy lol
I was going to put something similar, though It's already been stated. =o) Engineers of Tomorrow. =o)
I would beat their nerdy asses
Hope our future engineers have a little more going for them than just googling 'how to win earthquake tower comp'
I hope a similar video of engagement for differential equations class is also available. 😢
Wow this is so much cooler than the project we did. Our teacher gave us one little box of toothpicks and said "build a bridge with this and Elmer's glue" without giving us any lesson on architecture or engineering. Then he "tested" them by dropping a dictionary on them and telling us how bad we are at making things
This type of hands on and experimental teaching is what we need more of in America.
“Sorry, I don’t think I heard you correctly, but just in case I did hear you right your 275 F-35s are ready”
I'm Australian and Ive never seen anything like this it's unbelievable to think this is what schooling could be to me 🙄 all I learnt was 2+2 is 4 lol I went to almost every school in Australia and all they attempted teaching anyone was basic human common sense like if ronny eats an apple but had 3 how Many apples ronny got ? That's literally it. That or listening to teachers ramble more literal birth giving information
@@cod_is_dead4599 same
I live in America and in scoence class we do a lab like thing thats hands on like every week or so
so that's why americans bring guns to school. it's to prepare them when they go to countries with an abundance of oil 🧐
In Japan, this type of construction method for earthquake-resistant structures is common.
Yea it’s actually pretty common where I live in the Pacific Northwest to have some Japanese engineers help work on our high rise structures.
because you know, when fucking godzilla walks around you gotta have shaking resistant buildings
You mean with roll-y things in the bottom? Really? Huh how does it work?
@@rs-mt6kl they don’t literally use balls. That’s just a simulation. What I’ve seen are essentially giant pistons with rods in them that are attached on pivots. Unless I’m way out of the loop lol it’s been about 6 years since working in the industry
@@tylerbaxter4199 that's kinda what I figured, maybe some axle design where there's sOmething rolly attached to some longer bits but I couldn't imagine where the rolly part would be and what exactly it'd be attached to. Cool lol
The frequency matched because of the weights in the center. This is how they design high rise buildings to withstand earthquakes. This is awesome. Real teachers doing real things. No talk of gender or sexuality nonsense

Ahhhh yes. I hate it when my wooden archer tower is destroyed by a magnitude 15 earthquake.
Edit: When tf did this comment get 10k likes? lmao.
It was far more than 15 when it collapsed reality is it doesn't scale to real buildings the same way
nice one😂
I agree, iron hands.
Magnitude 100
Lol 15 Magnitude lol
This student actually took time to learn what causes the buildings to break down. But ensuring that it's not completely solid at the base, they've ensuring it's flexibility allowing the model to endure near the end.
experiments like this are what i loved for as a kid in school.... i was so glad when our foil boat held more pennies than any other in the grade
Nice! Reminds me of my first engineering class in college, we were divided into groups and we each had a major project for the end of the year...build a concrete canoe, any that floated went to the next round where we started loading people in and any that held a couple people would race to see which could not only float but which was the most hydrodynamic
I remember we had to build a boat that could both float and go under a bridge without destroying the bridge and one team made a boat so tall that it squuuuuuueaked under that bridge so close it took minutes. Not a soul breathed the whole time, I remember the jubilation when they cleared it. Wasn’t even my team, it was just so tense
we did clay and mine worked best looked like shit but sank after 50 pennies
Plot twist: kids been working part time as an
engineer after school
Na he just has bridge constructor on his mobile
Nah, he got 100% completion on poly bridge
I laughed so hard because the kid in the back looked away at the exact moment it fell off 😅 he quickly looked back when hearing the noise like shit... I missed it!
Lol
Hoe did the kid on the left even see? I'm not sure his glasses are helping.
Oh yeah that was so hilarious
Oh man I got to watch whole video again :(
that's that call of duty logic right there lmao
Ive had the fortune to build skyscrapers for a living. Seeing this was cool. Watching buildings 40 stories tall sway 10-20 feet in either direction is pretty wild as well
Coolest thing I remember was making tin foil boats and filling with pennies studying weight distribution
I remember winning the race we had after we made our own design and filling it up with pennies and putting them on the water to see how many would sink it mine didn't sink and had the most pennies in it pretty neat remembering that cause not really any other fun games like that to learn when I was in a hook sadly I would've liked school more
We had a principal of technology class in my school that was super fun we made cardboard boats and then took them into the pool to see whose boat would last the longest we also made Rat Racers using Rat Traps
@@connorstiles1001 we did the rat racers as well as a sail version and raced them down the science wing halls lol
I did that I school too I won that competition too mostly because I had been studying boats and how they float for a long time we got 33 pennies in before it sank the only reason it did was because of the weight made the water go over the sides
as a teacher i am so happy to see people get to experiment such things and probably they built the thing itself. very nice education there
I remember building one of those in school 24 years ago. This brought me back.
My life science teacher did not believe in "books". The first day of class... he said if he had his way they wouldn't even come out of the closet but the powers that be said he MUST use them so he issued them. I think they were on like the 4th year of use and they were still crisp and almost still had the "new book" smell.
Every Friday he passed out 1 page with 10 or so questions on it.. multiple choice and the Page#/Paragraph# where the answer was... took a whole 3-4 minutes to do it. Rest of the page was filled with his "pig portraits" that he drew of us... every week he pick couple students for the portraits lol. THAT was the ONLY time we opened our books each week. He assigned them on Friday and we turned them in on Monday. If you FAILED to turn in your "homework" on Monday, your "punishment" was you did not get to participate in "class" that week... you got to do that week's lessons from the book.
Class... was 100% "lab work". Learn about plants and such we grew them and even cross polinated them ourselves and how does that happen normally? We get toothpicks with a bee's ass in the end of it to polinate our plants.
Blood flowing through heart? No diagrams for us! He stop by a local slaughterhouse and pick up a ice cest full of pig hearts and we took a thick wire and threadded a heart the way blood is pumped through it.
Lungs, back to slaughterhouse and a load of rabbig lungs we put a straw in so we could inflate them.
Digestive system? Cow Stomach and intestines.
The man was... more like a "Mad Scientist". He even lived in Africa, can't remember what he did but it was with some group doing something over there. We would get stories from his time there.... like if someone dies you basically stopped what you doing and have the funeral that day if possible or next morning because the smaller villiges did not have electricity or refigeration or even a morge... sothey have to get them in the ground quick.
He had a parrot that was like 12-13 yrs old and for some reason.. one day it decided to HATE me and would do whatever it had to do to bite me... When he clipped the wings I thought I would get a break... but NOPE! That ASSHOLE would inch his way down his perch, walk to edge of counter, inch is way down the counter and drawers, waddle across the floor, climb up my damn leg... non agressive but matter of factly (thoght he might have got over it or something cuz it was just climbing and not attacking... till it got on my shoulder justr to BITE my damn EAR!! lol One day I forgot my glasses and NOTHING... was like I was a stranger.. we both noticed that and figured it was someone with glasses that did something to it... so I didn't wear them for bout a week and then the damn thing caught on and back to business as usual... Parrot dive bombing you but you cant hit his "kid" lol... so I came up with using my book as a "shield"... it dive bomb me and I just hold book up and let it dive bomb THAT and keep the flat edge ffacing it, slick cover = he cant grab on and a angle = he cant land so he retreat back to his perch and devise a new attack lol.
2 6' Boa's and a 5 ft. python. Python was a little "grumpy" but boas were super docile. One day a guy got the python and got nervous and threw him... a girl sacrificed herself and caught the snake so it didn't land on the tile floor and got bit twice... 3 big snakes? Gotta have a rat colony, they have to eat and its life science class... no pet stores for food, he raised his own rats. 2 of them 1 male and 1 female was immune to being snake food...
And 1 terrantula... and i fucking HATE spiders... ALL of them. But... when the girls are picking it up and playing with it.... lettin it crawl on their face/hair... now I HAVE to pick it up..... and that thing was fuckin COOL!!! lol
And at the end of the year we turned in our brand new 5 year old text books so the next class could get them and "not use them" :)
