I want to take a moment to thank those of you who support Smarter Every Day on Patreon. I'd also like to point out 2 things about this video.
#1. You'll notice Jeremy Fielding is in this video. He's the "Contraption Fabricator" that's started working with me now because of your support on Patreon. He's a great designer, father, and friend. You'll be seeing more of Jeremy around thanks to those who support at www.patreon.com/smartereveryday/
#2. If you'd like to 3D print the Snatch Blocks and pulleys we use in this video they are here: www.thingiverse.com/thing:4022579
#3. I really enjoy KiwiCo and I think you will too. I got them as a Christmas gift for my children years ago, and it was a huge hit. It was after that experience that I reached out to their team and asked if I could advertise for them because of how good it was for our family. I think you'll enjoy it too. www.kiwico.com/smarter
It was 3 things... I ended up pointing out 3 things.
I think showing the LENGTH of the rope you pulled with 2 pulleys v.s. 1 pulley will explain everything much better. It took me forever to finally understand. Maybe I am just an idiot.
Edit: It's like going 10mph(force) for 2 hour(rope length) vs. going 10mph(force) for 1 hour (rope length). You get more out of it. That's how I understood it anyway.
You also have to remember when setting one of these up that the max you can lift/ pull is the weight limit of the cable or pully
Hey man, all your videos are fascinating! Thanks!
I carry rope and carabiners while hunting to set up pulley systems to get large game up steep inclines. The input end also helps me climb up at the same time. Carabiners have much more friction, so they hold the load in place better.
Destin, You could have used a third scale, that would be holding the other end of the rope, the one that is fixed and does not move.
Also, It is very interesting how the flatten unfolded multi pulley was not moving uniformly, indicating each disc excreted different force. It would be interesting if you replace it with separate pulleys each one holding separate weight (all weight would be with equal mass).
People are really going to be really impressed when I bring snatch blocks to the gym.
This comment is underrated
It's more funnier when you can make a video of it
Love it
What did you max out on
Your comment is double entendre comedy gold.....well played sir

@@chayneznfayme Given he wasn't standing up straight, and could have been as young as 50, I'm sadly guessing he wore out.
A rule of thumb we always used for figuring out mechanical advantage for rope rescue systems was, if the pulley (or snatch block) is moving with the load, it is providing a mechanical advantage. If it is not moving with the load (i.e. it is attached to an anchor point not a part of the load) it is only providing a change of direction.
Yes this is true. Good way of thinking about it
This is how I learned it when setting up a homemade lat pulldown in my gym. You don’t want the system to give you advantage you just want it to offer resistance in the desired direction.
You also can’t afford having 2 to 1 ratios of distance. You want the weight to move 1 to 1 what your arms are doing. Otherwise you would have to double the weight to counter the advantage you’re getting. Gym equipment is, of course the opposite intention of many pulley hoisting applications.
9:08 so does this mean when they pulled themselves there was no mechanical advantage...as the pulley was fixed
@@HalleyRaiI was thinking the same
I think in this case because the winch is moving with the load it accomplishes the same thing.
Dustin... I just wanted you to know that I saved this video a year ago and have referred back to it often. This video is one of the finest examples of what makes your channel great. Entertaining, informative content that makes a person smile. You've really found you calling here and should be proud.
I totally agree with you Fred :)
After watching this video I was able to construct a pulley system with a 1300 watt winch and 6 snatch blocks that could pull medium size oak stumps out of the ground while preparing for a house build. Insanely satisfying to see the science work in real life. Thanks for this video. It saved me a lot of time and back ace.
I'm a year late to this question, but I'm less impressed with the pulley's as I am with *what they were attached to*. Was it the hand of God?
@@EarendilStar He had a 30 ton digger standing around which provided him with a handy Archimedean point.
Figuring out the best way to pull stumps is exactly why i clicked on this video.
This man could sell snatch blocks to a snatch block salesman
Well where do you think they get their snatch blocks from?
He eats snatch also

Man, your enthusiasm and excitement about physics is infectious. This is the kind of stuff that gets kids and adults alike excited about learning.
Agreeeed I used to hate physics never understood it until I started watching these videos they're so captivating and educational
I don't agree. He's impressed with the mechanical device without really understanding what makes it work. This is primary school physics.
frl
And what I admire the most that there are just so many sure signs that it's genuine! He approached random workers because they had a SNATCH BLOCK. Hahahaha!
... all over the world!
Yes pulleys are amazing but always remember the safe working limit of your cable / line / rope / strop etc quickly becomes the governing factor. Great production by the way, makes learning stuff fun !
Shouldn't matter much, As you get more blocks in the load your line load reduces. If you have a 4:1 setup then your total load is divided by 4 and that's how much is on each line.
So if you want to lift 1000 pounds a straight pull is of course 1000, a single traveling block causing a 2:1 pulley is 500 on each line as well as a 2:1 mechanical advantage so it both cuts the line load in half and doubles the pulling force, a 3:1 does the same its 3 times the pulling force and line load is cut into 3 so you are at 333 pounds per line. If you want to get real complicated you can factor in the angle at which each line is at and that chances the numbers as the farther from 90 degrees or parallel lines the less mechanical advantage and the less line reduction you have.
@@towtruckaj but you still have the line lifting a 1000lb object at the end of the day
@@ionbusman2086 not really, with my 4:1 for example you are effectively turning 1 line into 4, so it’s really one long line that runs through a bunch of blocks but it acts as if there were 4 because both your mechanical advantage and line load are effected, for each moving block in a perfect world you get double the pulling force and line load is cut in half, so for a 4:1 moving 1000 pounds you would need to pull with 250 pounds of force and each line would have 250 pounds of force on it, so to move 1000 pounds a 250 pound rated rope would work. It’s fairly simple until you start getting into the angles of the blocks and compounded pulley setups.
So yes in short the object weight doesn’t change you are still lifting 1000 pounds, but with pulleys you can move that weight with a lot weaker equipment and a lot less force.
@@towtruckaj But where the line ties to the 1000lb object, that's the weak point
@@ionbusman2086 what you are describing isn’t a proper mechanical advantage setup, to achieve mechanical advantage the blocks have to be on be load, if you have just one line actually attached to the load no matter how many blocks you have unless it’s a compound setup you don’t have mechanical advantage, for my 4:1 example you would have 2 snatch blocks on the actual load and 4 lines 2 for each block. What you could do if you could only attach one line to the load is have one heavy piece of rigging rating for the full forces then you could compound it and apply mechanical advantage to that one line, so like a 1000 pound cable sling with 250 lb rated rope in a 4:1 connected to that cable.
I am a Mechanical Engineer who once did a similar demo on the power of pulleys in my kids' Science class, but yours was way better! Love your enthusiasm for the topic!
This guy is the physics teacher we hoped for but never got.

@@SharpObserver1A could you explain then?

i had a physics teacher like him
My physics teacher had the same energy tbh! I wasn't great at physics but I took as much of it as I could because of him. Also he showed us Paul Hewitt physics vids!
I love hearing Southern folks around other Southern folks, our accents get 100x stronger. Destin is no exception
Have you heard Hannah Barron's accent?
I’m from Tennessee and I’ve noticed that everyone seems to do that. Is it like a subconscious peer pressure on how you should talk? I can’t figure it out.
I live in another country and speak a different language, but the same thing happens here haha
I’ve noticed this also. I have a little draw but it gets way worse around certain people. It’s like we’re trying to out-draw each other.
@@JerryDLTN I love her, have you heard Ginger Billy?

Hey Destin. I just used the "snatch block" technique with a come-along to get my tractor un-stuck from a pile of manure. THANK YOU for saving me from having to dig it out the poo! You really saved me.
Great stuff! As a young civil engineer, working for a bridge construction company, one of my regular tasks was designing critical lift plans. Basically, beam erection plans. They included selecting the right crane(s), and the required “rigging” (i.e. cable size, number of parts in the block and tackle, lifting clamps, etc. Your video brings back lots of great memories.
alright, i’ll be that guy.
“hehe, he said erection”

@@threestans9096 nicely played!
I would have died if the sponsor was SnatchBlock.
It so was
I was SO waiting to hear the sponsor too! They better give him something for this free commercial! LOL
I'm only 8 minutes in, and now I'm disappointed.
it a type of pully, not a company
My girlfriends mother is a snatch block
"Jeff is the kind of guy I wanna be when I grow up" Nice to hear sentences like this from a grown man with kids and a hugely successful TH-cam channel.
... Who's an engineer...
That really overwhelmed me! Destin is so humble it's almost incredible!
Man, it's a pleasure to watch him!
Hey Destin, I bought some Snatch Blocks after this video came out (Same ones you used). Never used them but I got to today! We used a double snatch to lift up a heavy piece of furniture up some stairs. Only knew how to do it because of this video.
You must respect the wires under tension. If they snap, they can kill.
just like Thanos do
Ok Can’t blame u if I want to shoot me lol
Well... Mythbusters kinda showed it's not That likely the get killed by a wire.. but never go under a load.
I noticed in the video when they pulled the jeep with the wench while it was in gear there was a blanket draped over the cable in an attempt to mitigate the force in the case that it actually did go down like that. Still a worthy note sir.
I seem to recall a video of Army engineers stepping ON the ropes of a multi-pulley setup if they had cause to traverse their setup. The reasoning being that if the rope did snap as it was crossed, the whiplash would be mediated.
Oh yeah, this is gonna be a good one. Love me some pulleys
Bill Pulley,hehe.
I love how dustin’s accent magically reappears when talking to other southerners.
From my personal experience that happens more or less per instinct and you have to 'snatch out of it' as an active decision.. 🤓🧐
Lol I’m from the Midwest west and I work for a company that does work all over the country and for whatever reason I start to talk like that when speaking with that southern accent on the phone. 🤣 no idea why lol. Same when I hang out with my hick friends 😆 I say creek but when hanging with them it turns into crick lol
I'm from Louisiana and people ask me if I live on the east or west coast, it's so weird
I used to live in the super deep south, but I've since moved to the Midwest. Sometimes I catch my southern accent coming out when I generally don't speak with one.
@@jonnyh3559 Code-switching
LOL I am from Cullman, Alabama. I feel you about most always coming across people who just have “know how.” I finished assembling a cheap small 2500lb winch today (welded it to an old truck receiver).. and how I have an old disc up in the woods I gotta drag out. Only have 1 snatch block… until tomorrow haha

@@PrimetimeNut I too was once an insecure fourteen year old who projected my insecurities onto the world around me as "cringe"
@@PrimetimeNut People naturally mimic those around them for different reasons. Don't hold it against them. In fact, if you can play it up genuinely, people like you.
first, thank you. your willingness to share the power of knowledge is much appreciated. So, years ago, we had a tow truck (an old P.T.O unit with a twin boom system) that we called the "School Marm". So named because on the side door of the equipment locker was the mathematical calculation required for that tow truck to right a capsized battleship. A single, dual line wrecker that weighed in at about 14,000 pounds and delivered maybe 250 horsepower carried the mechanical power to drag a hypothetical battleship, that would weigh in at more than 40,000 tons, back to an upright position, made possible by the mechanical advantage of the mundane pulley.
Well, that's my story. And i am sticking to it. Aloha.
40,000 tons?
@@callofdoobie3092Depends on the battleship. The USS Iowa for example can weigh 48-57k tons depending on equipment load.
Destin, that was maybe my favorite sponsor ad I’ve ever seen. I wish more companies were open to interviews for their sponsorships.
I love how much Destin’s accent comes out when he talks to other people from the south. Especially when he’s so excited about snatch blocks.
Code switching!
I wasn't sure who was talking at that moment 😂
accent ??

You've made me way too excited about snatch blocks somehow

I am so happy I was recommended this by TH-cam. This guy was fun, I loved the interaction with his kids, and all the visuals and everything about the way he teaches! The snatch block was awesome and now I’m thinking how I can use something like this at my construction job!
I felt like I was watching a really long advertisement for a product called snatch block
this brought me back to elementary school, we had some great teachers there.
It’s like snatch block and oxy clean/flex tape had a baby.
snatchblock!
If only all advertisements were this informative and interesting!
Tired of not being able to pull stuff up?? SNATCH BLOCK!
My first thoughts were, "well yeah, everybody knows this", but then I realized that most people did not grow up playing in barns and driving Jeeps. This was my introduction to "Smarter Every Day". Great video and Destin, you are a great teacher. My Grandchildren are going to be seeing a great deal of you. Thanks.
Idk. I haven't used them before but they just seem intuitive. I have no problem understanding how they work
Anyone who doesn't understand basic kinematic doesn't *really* understand. Kinematics is very intuitive, so it's easy to think you have a grasp on it.
Also, just thinking about a pulley or gear as infinitely many levers and focusing on one will help (your basically just rediscovering conservation of angular momentum)
However, there is always more to learn, even with something as simple as this. How does it scale, when do QM effects become non negligible. How much tension do you impart in each part of the system.
TL;DR
Learning how to use something and knowing calculations is fine for applied purposes. But rabbit holes are everywhere and can be fun to pull into.

Perfect timing. My Christmas shopping just got easier. Snatch Blocks for everyone. 👌🏼 😂
Can I be part of your family? I want one!
I have lost count of how many times I have watched this video over the past 3 years. I love it. I went to school for engineering so we studies this in our statics class. In an odd way, this is so much fun. In an interesting follow up to this video, how does it work if the load you are lifting is you? Say you are sitting on a board tied to a rope that goes up to a pull and the slack rope comes right back down to you. To lift yourself up, how much force to you need to apply? You are both pulling the rope down and pulling yourself up at the same time.
9:21 People of the internet! Please DO NOT stand that close to a cable that is under tension!
9:25 the jacket on the cable according to some old timers will stop the cable from snapping back should it break but I wouldn't wanna test the theory
I was cringing the entire time.

It works. Synthetic rope generally won't hurt you but can definitely smack you pretty hard.

Does anyone else have the impulse to buy a snatch block despite knowing you’ll never ever use it?
I thought so until today I wish I had one...
Yep, I got 5 or more, 2 are so nice I can't bring myself to use them, Keeping them new.
To be honest I’ll probably use it a lot
I have a lot of tree trunks to remove in the backyard. 200 pulleys would help
I suddenly have the impulse to create a pulley system that makes pedaling a bicycle in high gear much much easier.

@@wanderinwolf3804
If you just push the ground, you can already do that
@@wanderinwolf3804 a pulley is a lever
@@willsheehan2975 No a pulley is not a lever. a lever is a rig bar resting on a pivot point, called a fulcrum, used to lift heavy loads. A pulley is a grooved wheel which a cord passes through to change the direction of the force needed to lift heavy loads. Just because they are both used to lift heavy loads does not automatically make them the same thing, that is a false equivalency. Thats like saying a swimming pool and a lake are the same thing. They both hold water, they both can have living organisms live inside it, they both allow for swimming... So a swimming pool and a lake must be the same thing.
Your enthusiasm for science and engineering is contagious! We've got snatch blocks on our wish lists now! We have also loved kiwi crates, my oldest spends hours building and playing with the awesome things they send her. Thank you for your video.
By the condition of those Jeep tires, I’m surprised you didn’t get stuck on the asphalt.

At 9:00, there is a jeep pull example. How is there mechanical advantage by hooking the fixed end to the jeep and using a single pulley?

“Yo dawg, here’s your warship” is probably the best thing I’ve ever heard said on this channel
Destin has the knowledge of an old person and curiosity like a child.
SNATCH BLOCK!
I like when he said "when I grow up". He will be young at heart forever.
R'mur yeah! That’s what I like about him so much.
I am rail rated on an old rail system and this video helped me understand a little more what's actually going on when we use block and falls, it's a whole graded pully system! Thanks so much for this one.
I love how the accent kicks in when you're out of the studio filming with the locals!
I’m trying to design a system to get my wife’s manual wheel chair into her van without effort. You may have just genuinely helped in improving her quality of life. Thank you. 🙏🤝🤞
Hope it works out man.
Since you will be limited on space for a elaborate compound pulley system such as the one Destin demonstrated. I recommend looking into an inline compound pulley system.
Just remember though, the more pulleys used, the more rope needed to achieve the end result.
Good luck

SNATCH BLOCK
If I had not seen this video I would have assumed it was just another name for a chastity belt .
@@joemag6032 this comment is so underrated.
@@arielerosa3204 , oh well, later "Astrobrant2" posted a similar comment, and got several thumbs-up, so at least a few people are familiar with that old slang term.
Hi Justin. Love your channel!.
Little story bout leverage and simulated pulleys through knotted rope.
In 1988 I was working in a band and towed the box trailer round to our gigs containing our 1500 lbs of PA system. Long story short, the drummer owned the trailer and on one break we stood outside the venue at the cars where I said to Louie - you know what?, if I compounded the Truckies Hitch Knot on this rope to 2 and 3 knots in the same span, I could buckle your trailer. Louie said go for it. I tied the hitches together from one side of the trailer to the other side and pulled. Louie laughed at my attempt when a big CRUNK sound emanated from the sides. The trailer had crimped vertically along the sides approx centre of the way down its length. I apologised and offered to get him a new one but we bent it out and compensation went no further.
The reason I mentioned this is because I was fascinated that one rope can be levered so strongly. I tried 4 and 5 hitches in the one span but the nylon or hemp ropes would snap with just the smallest of force. I saw your vid a ways back and since have been wondering what it reminded me of. There you go. Take care M8.
TH-cam video: talks with slight southern accent
Talking to another Alabaman: southern accent triples in strength.
He applied some snatch block to that accent
It works that way in many places. Southern Michigan has a general midwest accent. Then when you go back up to the upper peninsula, your accent gains about 5 power levels and graduates to Yooper.
@@2009dudeman it also changes when we visit Canada.
Thats because he had SNATCH BLOCKS to triple his southern accent.
I didn't notice till I read your comment.... being from South Ga it sounded the same to me 😁
its kinda like gear ratios, they multiply the torque at the cost of speed.
Not kinda like gear ratios. Exactly like gear ratios. The only difference is the directions of the forces.
And technically, since you most often think of gear ratio in terms of vehicular motion, even the directions are not that different. Input is the vertical movement of the piston head. Output is the force applied to the road.
So a pulley can create a ratio and change the direction of a force. While a gear can create a ratio and reverse the rotational direction of a force.
I noticed that too, I was wondering why it was so slow, but when he was moving the truck with a winch, It clicked since it took so long.
@@codeman99-dev it's also exactly like a lever and fulcrum lol. The ratio between thee distance from the end to the fulcrum between both sides is the ratio of force increase. You sacrifice distance for force and since distance is proportional to speed, one side of the lever will move faster than the other.
Instead of rpm you calculate the speed it takes for the end of the lever to go from top to bottom, since they both go top to bottom at same time but one goes a larger distance, there is a difference in speed. Plus change in direction, one side goes up, other side goes down. One gear spinsclockwise, other gear spins counter clockwise.
When you think about it, a gear is just a lever spinning around its fulcrum, and pulleys are just gears connected with ropes.
All types of mechanical advantages are the same concept really.
Or Pascal's Principle.
I know you're right but I don't understand why. All the wheels on the pulleys are the same size.
I love how happy Destin is with himself when he spins his model around for the explanation.
Dude, I think this video has the funniest ending. Awesome content and... Snatch block! 😂
Destin: "Pulleys are like my favorite thing in the world."
Laminar Flow: "Am I a joke to you?"
From the literal standpoint is laminar flow not a thing... :o)
Literally stole my comment before I could make it, almost word for word!
next video: laminar snatch blocks
Literally the comment I was going to make... xD
Yep, I was scrolling down till I saw a laminar flow comment.... didn’t take long, thank you!!!
Destin: "These are like my favorite thing in the world"
Laminar Flow: "am i a joke to you?"
prince rupert drop to laminar flow: i get it
Destiny’s wife like am I a joke to you
Crustcheese THANK YOU!
What really clicked for me was when I realized where the trade-off in the effort was. It's not magic. As you double the force lift you must also double the distance the rope travels. Need to lift a 100lb weight 10 Feet? With one pulley you can make it feel like a 50lb weight, but it needs to be pulled for 20ft. Two pulleys make it feel like 25lbs but 40ft of "distance". all the way down to making the load feeling like it only weighs 1lb but you must make that 1lb weight travel 100x the distance. This idea preserves the energy in the system. You're still expending the same amount of energy, but in a less intense way.
Excellent understanding
Not quite the same as you loose a little energy because of friction.
Snatch Block!
simple high school physics
So that means in each scenario, the work done is equal. As work equals force x distance.
I love my snatch blocks. I have 4 of them in my Jeep. You just explained the magic of why mechanical advantage works. I always wondered how anyone discovered this and why does it even work. It's not magic, it's the constant tension! Awesome.
"I'm really good with pulleys and stuff"

I can't remember what that reference is from though.

@@traycarrot What does a SOTA warship cost? Compare that to the average budget of a scientist (hint: one is less than the other).
@@DagarCoH archimedes wasn't the average scientist
i like how destin dials up his alabama accent when talking to jeff
Being from Tennessee but living in San Diego I do the same thing when I’m back home and I INSTANTLY noticed that.
his alabama accent went from 0 to 100 FAST
I came in here to say this.
That can happen subconsciously. I've noticed that I tend to reflect the accent of people I'm around if I'm around them for prolonged periods of time - even if I'm still living in the same place as I was before I started reflecting the accent.
My dad does the same. I dont have an accent. and he doesn't when he talks to me other people generally. until he talks to his family he reverts to a pretty hefty accent.
I felt like I was watching Sesame Street for adults... "The word of the day is: Snatch Block" "Lets count the ropes! ONE... Ah! Ah! Ah!. twoooo... Ah! Ah! Ah!"
It was wonderful.
he can totally rename the channel to that
His video on Laminar Flow was just like that as well lol.
The front tires on the jeep have seen better days 😂. Love your videos!!!!
Dustin, can I just say that I thought your sponsor was amazing, the first time I ever watched the whole advert bit, what an honest and worthwhile company :) times are a changing x
Awesome explanation and fun, this rocks! Something I just realized phenomenal about a compound pulley you demo, is each pulley could be tethered to SEPARATE objects to divide the load. So if you had weaker trees, you could tether to separate ones and still get the job done!
Dude modulates his accent heavily depending on audience. Fairly nuetral for TH-cam, and thick southern for roadside truck help.
I'm the same way if. I'm talking to someone with a southern accent it brings out my accent.
Most Alabamians are quite similar. It’s a way of relating better with the older generation and the uneducated.
Scottish here but yeah, 100% anyone with a strong regional accent has to modulate when talking to an audience from outside the region. Used to live in a flat of 3 Scots, a Dutch man, a Spaniard and a French man, all fluent English speakers. Still, no one could understand us when we spoke between ourselves, so we all had different accents for speaking as a group.
And that's a wrap on the snatch! Good video!

* SAD LAMINAR FLOW NOISES *
😆😆 I feel Laminar Flow's pain
You beat me to it ;-;
I'll never forgive public schooling for wasting a year of my life to try and fail to teach me what is easily communicated in a 15 minute video
School reiterates concept after concept over time to force you to memorize it, the chances of you remembering anything other than a basic principle from a 15 minute youtube video is slim. Why do you think you can remember how to spell even though its been years since you were first taught?
@@Nick-bb4nk My original comment is about knowledge vs. understanding. Reiterating the concept until it is beaten into your skull grants only limited knowledge unless extra effort is undertaken to actually understand the underlying principles at hand & their applications. This video enables people to move past that barrier, unlike most public schooling in the U.S., which incentivizes blind memorization and regurgitation to prove competency, instead of actually promoting learning. Hope this helps!
@@Nick-bb4nk Because we have practiced it since school? Doesn't take much work for us to go play with pulleys a bit and get that YT knowledge ingrained. We'll remember that much better having not been browbeaten into memorizing it, but rather internalizing the learning.
Okay then, you should be able to teach your kids how to read with a 20 minute video on youtube and letting them play with block letters.
@@Nick-bb4nk Nice example of oversimplification there Nick. Happy to discuss this further when you care to do so reasonably.
This felt like some weird SnatchBlock™ infomercial. I'd buy a couple.
SNATCH BLOCK! It's for kids.

I’ve been 4 wheeling for 45 years, this is the BEST explanation of snatch blocks and mechanical advantage that I have ever seen. Your enthusiasm exudes too! Thanks YOU. Going to check out KiwiCo for my 5 year old granddaughter
"These are like my favorite thing"

A rope's flow around a pulley is laminar.
"Yo dawg, I hear you like pulleys."
Never knew I needed to hear that today.
Destin is an OG memer
"I attached a pulley to a pulley so you can pull while you pull"... well, it does make sense.
Destin: (pulleys) are my favorite things in the world
Laminar Flow: *surprised Pikachu face*
LOL That thought crossed my mind too
*applauding*
Well you can say laminar flow is a "phenomenon" and pulley is a "thing"..
Thanks for the video! Best pulley explanation on the Internet!
"Dad, am I your favourite?"
"No, son. This snatch block is my favourite"
"Then there's laminar flow, slow-mo cameras, dominoes, Prince Rupert's drops, eclipses and of course rockets. But I'm pretty sure you're on my Top 100... I guess."

Hey I was working on a problem at my job and didn´t know how to use pulleys. Now I know, thanks to your video and I solved the problem. Thank you.
I like that when you're talking to Jeff, your accent kicks in. You sound like a regular guy in the video until you start talking to another southerner, then you're twangin left and right all of a sudden. Same thing happened to me all the time when I was going to school in Texas. Grew up in the Pacific Northwest, didn't have any accent at all, but when I met a real Texan's Texan, I'd subconsciously put on an accent so they'd treat me like one of their own.
I remember once I was on someone's property (unbeknownst to me) when the guy comes riding up on his horse with a rifle in his hands, said "what are you boys doin on my land?" to us. I responded in the most Texas accent ever, responded "Sorry sir we didn't realize we were on private property. We're from UT, out here looking into a report of some sorta parasite that's been livin' in the streams and killin' cattle." The guy clearly figured me for a good old boy, sounded surprised about the parasite, told us we were fine to be on his property "so long as you keep me informed about this here parasite". There was no parasite, we were out there looking for lizards, but the quick thinking and the thickly laid on accent really did the trick.
you passed a real life speech check
lol was definitely thinking the same thing about his accent. I'm from Kentucky and the drawls definitely comes back out whenever I'm back in the state. I call switching like that "the drop."
Vibe check irl
Rolled a 20 for performance
its called code switching.
When using a shackle, always have the "U" section on the part of the load that may shift. Example of the "wrong" way at 12:31. In certain situations, running rope over the Bolt will actually cause it to unscrew and release the load.
Obviously not imperative for the operation going on in the video, but good information to share nonetheless.
I had always heard that but never knew why. Thanks
Great info...
(edited to add query reason*): I'm perceiving the rope as trying to straighten out *horizontally* (vs. vertically)...which begs the question: what happens if the fixed anchor points are allowed (or forced) to slide sideways?
* asked here because there are so many comments I want to ask somewhere it's likely people with experience (e.g., like the OP) will see it.
People these days: "How could people centuries ago pile up these huge Rocks on stonehenge?" Foreman back then: "We need more Pulleys!"
actually its super easy barely an inconvenience... oh wait wrong reference. ;D
