  • 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.

    • @melanieenmats you are right. Gears and pulleys are just more sophisticated levers. And with lever you lose distance but you gain force.

    • @Ying Yen Lin It is basically a lever. Pulley is just a divider so if you have regular pulley (one wheel i.e. 2 ropes coming out of it) it means that your pulling force has been "doubled". Work carried out of course stays the same so your weight getting lifted traveled only 1/2 of your pulling distance. Adding another pulley to the setup again doubles the pulling force so now you would have 4x the force but only 1/4 of the pulling distance.

  • I got a story form trucking in Michigan so in Michigan trucks can be 80 ton gross and no permanent so this guy gets his 80 ton tanker trailer stuck in a ditch and gets him self out by using very big rope pulleys and raping one drive tire to make a winch and pulls the hole truck and trailer up onto the road i think he said was out in like 45 minutes

  • A pulley is basically a lever on an axl. But instead of a longer lever you just need more rope and pulleys.

  • It's called the working factor... the formula is... the number of ropes on the movable sheaves is the working factor of the set of blocks...if 2 ropes are attached to the movable sheaves the working factor is 2:1.. if 4 are attached its 4:1 and so on .. 8 on the movable sheaves is 8:1...you get 8 lbs of pull on the movable sheaves with each 1 lb applied forse on the pull rope... hence an 8:1 working factor

  • all of this and he doesn't explain why pulleys work. They work because the length of the rope that flows through pulleys gives the same physical advantage as a lever. A pulley is a compact lever.
