      Snatch Block! 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.

        Did the ancient Egyptians know about compound pulleys?

    2. Zane A

      I thought this was a SNATCHBLOCK ad, but apparently its sponsored by Kiwi or some other fruit. Anyway, I have nothing to lift, but I feel like I need to have at least 5 snatch blocks

    3. Timbeera Titan

      I need at least 10 Snatch Blocks

    4. DLStarbuck

      It would be great to see the digital scale at each one of the pulleys.

    14. Water Under The Bridge

      I feel like it’s a similar effect to changing gears in say a bike. By adding one pulley, you have to pull the rope twice as far as before ‘cuz to shorten the distance of the object to the ground by x, you’d have to “shorten” the rope the object is hanging off by x on each side of the pulley (i.e. 2x). That means the same amount of work is divided into more distance, making the work necessary for each unit of distance smaller than before, similar to how switching to a larger gear will divide the necessary work for the bike wheel to make one revolution onto a larger distance for you to pedal. Also similar to how having a larger lever will divide the work necessary to lift an object (i.e. the distance of the lever to, say, the ground) onto a bigger distance, so the absolute work necessary per degree of the lever angle stays the same but the required distance to move that degree increases so you need less force per unit of distance to the ground.

    15. Akash Verma

      Pulley works without violating the energy conservation. Pulley reduces the power to complete a mechanical work but does not affect total energy required to do that mechanical work.

    18. cotes42

      He didn't state one time, not once, the importance of noting the maximum strength of any of the ropes/pullies/snatch-blocks/winch. Like he just throws stuff together and hooks a truck up to it. That's potentially very dangerous, because people might try and follow it, slapping straps and winches together and pull on things. It's all fun and games until a cable snaps and takes your face off.

      Какой тупняк. Это проходят в школе. "Выигрывая в силе - проигрываем в расстоянии". Система называется ПАЛИСПАСТ.

    37. Jean-Pierre van der Merwe

      The same thing happens with gear reduction basically

    38. Phil Goodhusband

      So here’s what I learned from watching this: 1. There’s a limit on the distance limit if you use block and tackle - you risk derailing the rope at a certain degree of roll/tilt of the block.

    39. Phil Goodhusband

      1. What are the loads on each of the hooks foxed at the top? 2. What are the loads on each of the knots?

    40. Khazadrim

      Este es un video super genial, creo que hasta mis hermanas pequeñs pueden entender los principios fisicos de la polea y el como aplicarlos; hasta me has dado ganas de buscar hacer videos como este pero en español y asi poder transmitir conocimiento a jovenes en latinoamerica y paises hispanohablantes, solo tendria que buscar el financiamiento de alguna menera. Muchimas gracias por los videos que haces, me inspiras a retomar estudios sobre fisica y el buscar transmitir esos conocimientos. Gracias

      I thought this was Bill Burr doing a bit

    42. Midas 2.0

      they definitely did snatch my blocks.

    43. goodtogoace

      you have to reeve the blocks correctly to stop them from pinching or twisting. trying to use them the way you had them in a real situation will create binding and feel heavier and not operate as smoothly. for instance, you'll probably have to use a tremendous amount of force and time to pull them back apart once pulling them together, as one side will obviously move faster than the other. when reeved correctly i can lift things by myself that takes two people to pull when they're not set up correctly and when pulling apart, the bottom set drops evenly.

    44. александр пушкин

      В школе объясняли все это очень просто-"Выигрываем в силе,проигрываем в расстоянии".

      So basically it's a gear-box. Less distance, more force.

    55. MagJib 99

      This video is so cool! Have been coming back here every once in a while because its so satisfying to see pulleys in action. Another wording that I would use for 2:45 is that the cinderblocks were held with 2 ropes with equal tension (thanks to the snatch block), so now each rope takes only 1/2 of the load (the load is distributed equally to each rope). Follow that one rope to the kids are pulling, thats why they can lift the same cinderblocks with only have the force required. And yes as they said, with the pulling force the kids are exerting now, and combined with that pulley system, they can lift 2 times the force they exert. Now i want my own snatch block.

    59. Yuriy Klimov

      Если через поднимающийся блок провести горизонтальную линию, то блок можно представить как рычаг. С одной стороны не подвижной верёвки будет рычаг закреплён. С другой стороны подвижной верёвки вы прикладываете силу к этому рычагу, а расстояние между верёвками, где центр блока и зацепляется крюк, как раз делит пополам, ровно в два раза.

      Wonder what would happen if you had like 1000 GIANT sized snatch blocks and they were connected to a ship. How many people would it take to pull up the ship.

    68. Luke Augustini

      Years ago when I was doing my rigging course one of the practical tests was rigging up a big old generator and up a ramp only using pulleys. Some old Ukrainian fella was in the class with me and kept doubling up the lengths of rope telling stories about how they’d have to use pulleys to move tanks after the war. Our team had the fastest time on the test and he was a legend for a day!

    75. Volvith

      Twice the work, twice the power. Once you get that, it's just a matter of solving the puzzle of how many times you wanna pull back and forth, and where you connect the start and end of the rope. EDIT: Also fun fact, you can lift a 12 ton boulder with a rope pulling itself down with it's own weight if you have enough pulleys. Yes, pulleys can basically invert gravity.

    76. Tony Gomez

      I feel very proud to see people who take the initiative to involve new generations in projects that stimulates their mental and occupational growth. Thank you very much for your video and the presentation of Kiwi Co. They seem adorable to me.

    77. wouldnt you like to know

      Of course snatch blocks are awesome. They are named after two other awesome things, so they have a lot to live up to.

      First rule of working with a winch: Do NOT stand in the Death Zone. This video may make you smarter about snatch blocks, but it will be hard to use that knowledge when you are dead.

    89. FCook

      Aha! Awesome video! One thing I learned homeschooling was that a pulley (any wheel and axel for that matter) is just a series of levers organized in a concentric way. Think of that! A wheel is actually an infinite lever with the fulcrum being the axel!!! So the same principle that applies to a lever (force vs distance) is applied on a pulley, only that the sides of the lever are always equal (and there is some added advantage by the rope gripping against the curvature of the wheel, which I don't know much about). That totally blew my mind as a child! I think you could include that in this video for us simple-machine loving people. Blessings.

    90. Dara Samudra

      Sangat terbantu

    91. Lang

      You're supposed to guide the snatch, not block it.

    92. Mike Yurchison

      i had to grease my wifes snatch block earlier. it hasnt been pulling its weight

    93. Joshua Young

      There's an even easier way to think about this that has helped me wrap my brain around the concept. With a single pulley, the amount you move the rope with your arm translates into the amount that the object moves. With two pulleys, the amount you move the rope with your arm is twice the distance that the object moves. It still takes the same amount of energy needed to move the object the same distance, but you're spreading out that energy with half the force required. At least that's how I understand it. Basically the same concept as leverage. When you have a long stick and you are prying an object, you are moving the end of the stick your pulling on ALOT, whereas the other end of the stick is only moving ever so slightly, but with massive force.

    94. Darrel Barnett

      I thought ancient egyptians invented the pulley system to help build the pyramids?

    95. Elina Malina

      uh .. why did this video get featured in my recommendation? I live in Russia and it is not very interesting to me and I do not understand anything. ============================== эм.. почему это видео попало в мою рекомендацию? Я живу в России и мне это не очень интересно и я ничего не понимаю.

    96. DA7545

      Say you have 2 blocks, 5 lbs each. And you want to lift it 2 feet. One pulley arranged to redirect the force to straight up vertical (1:27). You pull for 2 feet and it goes up 2 feet. Now set this up - (2:11). Now you pull for two feet and the blocks go up one foot. You did half the work. You have to pull, less force but over more distance. Easier work but more of it. You have to pull another 2 feet to raise the blocks the second foot you want. Less force required over more distance.

    97. LightManager

      Чё, там реально правило рычага объясняют натяжением верёвочки? Ох капец. Или у нас уже тоже самое?
