"We don't have time to discuss them here" Do you have something else to do? because I'm open for a longer video.
Time and the world as you know it has come to an end. Was it not your sin trapped the unicorn?
Syd G sounds scary, but I’m in the tire recycling business and up for a challenge! 😂
He had a retaining wall to build. He had to go!
Yep. Maybe because I already know a fair amount about the subject, but I thought it was pretty lightweight. Tried to put myself in the place of a high schooler (of which I am the parent of one) and I think they would've been bored too.
I wonder who the intended audience is?
lol. That's what I'm wondering. Maybe he's in a hurry to get home to his wife before Enrique gets there.
Why yes Mr. Algorithm, I did in fact want to watch this.
ciknay lmao, same thing happened to me.
*You're both welcome.*
Thank you that has made my midnight
Who else is watching at 4am when this was recommended..?
Yeah... scary! Me too!!
great video! thank you!
I love the Engineering behind all structures. From basic engineering to the extreme complex engineering.
I lose track when it gets Into deep equations, I get a lot better understanding by watching videos than trying to read the equations.
Thanks, keep going with even more in depth videos.
Make the shape an upsidedown T shape. Checkmate.
That's just a waste of materials. You won't get significantly improved performance.
RTYB its a joke :/
@@RTYB yes you will. In this example, it's clear. An invert t-shape is MUCH harder to overturn. Just try it yourself and see. And I'm only talking about this model, not real world construction, obviously. That may or may not work in the real world (different materials, etc.)
@@visualstudiosproductions Sure, it does. It shifts the toe further from the weight, making the moment arm longer, does opposing the overturning moment (called righting moment). But, if you had to add that piece of wood, it is better to just put it on the other side, extending the length of the horizontal leg. The results are better, I did the math.
It actually have been used in real world.
I love this video. In my engineering class, our lecturer explained this so badly. The class was pissed off by the confusion. This video is visual imagery of models made it explain clear. Awesome.
As a designer of bespoke rental properties, I love these videos. We always wonder these types of questions when building and just end up testing both to see which ones better over the long haul. In these videos, you do the research for us. Thank you so much!
So you guys are busy building and every now and then you're natural curiosity ends up demolishing another construction site?
Are you on fixed salary or piece rate?
@Swat Are you really a "property designer" who finds engineering solutions via simplistic marbles and plywood videos? Do you work for your dad?
@@waynebrinker8095 what's wrong with working for his dad?
You should hire an engineer. These are not just research, these are established principles that we have studied and every engineer should know.
This channel randomly appeared on my feed. And I’m glad it did!
Where has this channel been all my life? Awesome!
Am I the only one who wanted to see the L facing the marbles without the additional friction?
possibly! XD
it would just slide like shown earlier- kinda pointless to see exactly when that is when your goal is to build a functional retaining wall
There's no time for that here.
it will slide too
@@AndreasChristianto Yeah, I was just hoping for a direct comparison but they included the friction pad which ruined it
@@rogerscottcathey lmao 🤣🤣😂
this channel is extremely underrated, should have a million subs.
Thank you......The video was very much usefull and simple
I am persueing engineering and I am glad that I chose the ryt option in the beginning itself !
Realizations are something which keeps you motivated!
Thank you so much!
Your videos are GREAT!!!
where have I been for the past 3 years - thank you, good work
Very useful in determining how I'm going to construct a retaining wall on my own property. Thank you!
*Clever engineering* that helps to build our infrastructure.
A lot of nice and honest work in this industry.
I can feel the urge to know more about retaining walls growing inside me by the minute! Don’t you ever starve the mind of a professional procrastinator!
I'm so happy I found this channel!
Really interesting and artistic way of getting the point across!
Good job mate..
I think we can all agree that this is one of the best L shaped retaining wall vids on youtube. None of that H or S or even T shape bullshit here
TATERTOTS JACKSON Sphere-shaped walls are the best if you keep the water inside.
Yes, this videos lacks a bit of practical use.
You will make common man with good civil engineering aptitude. God bless
I am an architect and I really love your videos! Good job keep it up :)
@Syd G I had structure lessons during my studies and I saw all of this but never illustrated like this .. I think I would have done better in my exams with illustrations of statics like this. This kind of video should be shown in university.
@Syd G I mean it's basic statics... I'm sure it'd be a waste of time to spend any amount of time on retaining walls if you already know how to calculate allowable and actual moments.
I am a beach bum, but this kind of video still releases dopamine and keeps me from thinking of the meaninlessness of life and suffering for a minute or two. Plus it's way cheaper than heroin.
Dude you are awesome. Its so easy much easy understand the engineering concepts. Thank you for your effort.
i'm on the practical end here; i build them.
when you make a retaining wall you would increase the length of the
L leg with increasing the height of the wall (as said) ALSO you make the L leg thicker
both of these will counter the tendency for overturning or collapse of the wall.
if the wall is over 6' we normally will have some footing extend past the vertical
part of the wall (like a upside down T)this moves the tipping point 'Q' further from the vertical leg and increasing the stability of the wall
Cool, thank you. I was wondering asblout that!! So the T shape does work on both issues!!
Wrong
wowiezowiepowie can you tell us about utilizing different/lighter materials between the wall and the land being retained?
@@freeaudiobooks7469 Not helpful.
Free Audio Books your one word reply speaks volumes of your lack of understanding of the problem.
Oh wow this was one of the best videos on retaining walls.
It’s a Sunday morning...I’m not a landscaper or engineer and here I am glued to my screen on the edge of my seat watching a video on the physics of a retaining wall.
Great video.... I would love to see more retaining wall models... like gabion wall, buttress wall etc.
GREAT SCOTT!!! how in this world have I found this channel ONLY TODAY???
Thank you for your precious content. This is PRECIOUS!!!
Greetings from Portugal.
Very carefully made video. Thank you!
I love this explanation, great examples 👌
Don't know why this channel stopped posting, videos are good, easily understandable
Have I really gotten through so much of the entertaining content on TH-cam that I'm now watching retaining wall videos just to pass the time? I guess so... huh
Awesome video! I wish I had these videos during college
Simple and informative. Subscribed.
THANKS GREAT VIDEO YOU TEACH US IN A SIMPLE AND PRACTICE WAY.
Short and sharp! THANKS
This is some fine stuff right here, mate
This was the first video of yours I have watched. It was great 👍. The binge begins
As my MIL's family would say, "Oh mine too." Glad to have found this channel. :o)
Same I loved it! The kind of casual education in engineering I need!
After a strong diet of memes and funny videos, the algorithm still was able to figure out I'm in fact an Engineer
It's very useful information for me!
Thank you TH-cam!! -__-
You should link the extra videos in the description. Makes them easier to find and follow.
Thanks you. This is very helpful. Keep up the good work.
John Rex Alegria it’s thank you with no (s) on thanks you ........
Great explanation of how the forces acting on a retaining wall work under 5 minutes.
Thank you, great explanation!
this series is very useful. thanks
Brought back the final paper of my soils engineering elements vividly to mind.
Selected all three of the values from the Terzaghi curve from the bottom line (engineers will understand this) and proudly announce the retaining wall was going to fail in overturning.
It didn't, I did, along with two other students who made the same mistake.
In the pub afterwards our lecturer, who had been walking the room invigilating, said he'd spotted what we'd done but couldn't say anything.
We were allowed to resit the paper and move on.
Can anyone point me to a video about retaining walls that DOES go in to depth about the subject of retaining walls?
There are lots of them, but in lecture style. These are helpful during college days.
Try practical engineering
Dont think he has a video specifically about this but he does a good job explaining engineering stuff in a fun way
A fluid mechanics book will help. Look up forces on submerged surfaces
I do not have time here to send you a link of such a video... haha
Design of concrete structures 13 th edition by Nilson
I mean this was the 1st video that caught my eye and now I'm dying at the end!🤣
I'm not engineer but this was so damn obvious and logical
It pissed me off bc i felt like I was watching a vid for a 4 year old
If you think about it, a LOT of civil engineering principles are obvious through simple logic. For the math to really stuck in the mind, we had to fully grasp every aspect of this simple logic. You'll be surprised by how many huge and complicated structures are backed up with REALLY simple logic even for kids. Don't underestimate these explanations, because these can change a civil engineering student's semester.
@@seriyooow310 I completely get that, I just thought making a video about this and showing such a simple concept that I think anyone should understand immediately is useless. Especially since at the end they don't want to go further with the explanations of different walls because "we don't have time"?
r/iamverysmart
The best solution to a problem is usually the simplest one
Well explained. Thank you!
Wow! Great explanation and interesting channel. Thanks! Subscribed 😉
Excellent video!!
Good information!
Thanks !!
Best practical video..👍
Yes, we have the time! And we will be discussing them here!!!
That is so cool. It is the same principle with many bookend models.
I dunno why youtube recommended me this vid, but I enjoyed it :)
I've built a few retaining (gravity) walls in my time but I'm finding it more and more difficult to find enough marbles for back-filling. They come out through the 'weeps' in the wall too. Could you suggest an alternative?
Liked, Subscribed and Commented... I was searching for a video that would help me visualize and understand retaining walls, I suppose a genie nearby was listening and granted me my wish. Amazing Video Keep it up !!
Its very helpful.. thank you!!
Most useful resource I could find so far!
This is the type of video that excites others to get into structural engineering. I know nothing about it but would have loved to learn it and practice it.
Se puede incrementar la resistencia al deslizamiento de un muro añadiendo un dentellón en la base. Y es interesante señalar que parte del peso que deben soportar los muros de contención sirve también para darle estabilidad si se acomoda la geometría de forma adecuada.
So fresh and nice when the algorithm suggests something like this. Thank you!
I always heard about a "heel and foot" in building a wall footing, where the the load side is the "foot" and a short "heel" also extends away from the load side -- like an upside-down T but with one short leg. It is more concrete of course -- but is that design preferable?
This is what i was looking for. Thanks sir
Certainly helps with my construction management subjects 🤣thank you TH-cam recommendation
I support this channel. Please do engineering model on retaining wall with counterfort model.
Excelent explenation!
Супер, дуже доступно і наглядно. Велика вдячніть. Підписавсь, буду спостерігати за вами.
Pretty dam interesting.
Thanks.
I'm convinced it's a major contribution to road safety
A T footing would require more leverage to overturn and provide an increase in friction capabilities. Excellent point!
interesting.... Dead man Wall also a good design for retain pressure.
Geogrid mat is more easily incorporated between courses and material doesn't degrade
Thanks for making this video which is so useful
Nice video to use an inverted wall you have to check if the soil pressures are under the allowable limits this type of retaining wall has problems with compression of soil failure.
VERY INFORMATIVE AND CONCEPTUAL
Why you guys stopped uploading content...it is so good and you have good success too with this TH-cam channel.
Cool video liked and subbed👍
OK first of all why am I here and why am I watching this at 5 in the morning
I have often asked myself the very same question, although as often as not, cute baby animals were involved.
You never know when you you have to build a retaining wall. Better be prepared:p
im here 2:05 in the morning
brilliant video .. thanks
Grt... grt grt.
Loved it..
This video really is beautiful
We are just scratching the surface here but great video. Engineering is fantastic
Best u tube channel
So creative explaination👍👍
Finally, the youtube algorithm brought me to something I really want to watch
Awesome work
i knew it
the right one
nice one :3
Damn I wish schools were teaching like this!
That was interesting!
Hey that was simple and cool! What about the best of both worlds, an inverted T retaining wall?
(Timestamp: 2:30) My answer: I went with the "pointing in" wall (right) instead of the left wall at first. My reasoning was that the marble's weight would push down on the wood sticking inwards and leverage the wall to stick upright longer from the extra force.
Edit: I was close- I used improper terminology and worded my response weird, but I had the general idea down. I also didn't realize that the downwards pressure would also increase friction! That's a key detail to miss. Close, but not exactly. 3/5.
Great video
superb..
Thanks TH-cam algorithm! Enjoyable
Round back fill, like marbles will move. That's why it is best to use angular aggregate, because friction will be created. Try tossing something on a pile of round stones, and then do the same on angular stones.
Need more videos about cantilever bridge,slab bridge,cable-stayed bridge, Extra dosed bridge mechanism. Also need mechanism of cantilever retaining wall and other types of retaining wall.
I get you. It would've been great if videos like these existed back when I was still in college instead of another lecture from an indian (which I'm still thankful to, it's just that it's full of math instead of simple logic).
BRB. I have to go fix a retaining wall!
