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 https://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: https://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. https://www.kiwico.com/smarter It was 3 things... I ended up pointing out 3 things.

Stupid science Science doesn't know Jupiter growing up to create the Sun. The Earth is about to have two Suns. The Earth is constantly expanding, Evidence is that Hawaii volcanic lava is constantly erupting, Jupiter ' s magnetic field is 20 times stronger than the Earth ' s , so Jupiter expanding is 20 times faster than the Earth, Jupiter future grewup creating the Sun

I should add I got what was happening when I looked at it like pulling shoelaces taut. The two sides get closer together, but they move more slowly than the shoelaces which you're pulling on. Another comparison - pulling the drawstring on a pouch to close the opening. If you think like me, that should help.

Instead of thinking about tension, think about the fact that work = force x distance. Each time you add a pulley, you're allowing the person exerting the force to move a longer distance to lift the weight the same distance. Notice in your models how every time you add a pulley the weight is lifting a smaller distance as you move your hand the same distance? This means you are able to do more work with the same amount of force, or advantageously the same amount of work with less force. This is actually the way all mechanical advantage works. Same with levers (a pry bar) same with gear ratios (the same engine can't start your car moving in sixth gear, but it can in first).

My understanding on the mechanical advantage with a pulley is it is only gained if the pulley is in motion. For example, when the Jeep was "stuck", the winch capacity was not double by using a winch block. The direction of the pull was simply redirected 180 degrees (AKA the pulley was static). You will notice for ever 6 inches winched in, the Jeep would move the same distance. In the case of a true mechanical advantage, the winch line would have to move 12 inches in to move the Jeep 6 inches. However when lifting the bricks under the ladder, there was a mechanical advantage gained. Am I thinking about this correctly? @SmarterEveryDay

I first found theory of pulley's in my high school physics book. Teacher had skimmed that topic and no one bothered to ask much questions. Then I saw a reference question explaining compound pulley. It blew my mind on how force was being multiplied. I understood the maths, but couldn't accept on physical terms, how the force was being multiplied. I completed the how question bank on the pulleys using maths and yet couldn't understand where/how the force was being multiplied. At this point, if I was given a pulley design, I could tell how much force multiplier would be there, but I couldn't have designed the pulley design myself. It irritated me a lot. A few years later, when I was passing time watching clouds, somehow it clicked. It was due to the length of the rope and it's movement. That is the physical thing that is multiplying the force. 4:30

It like if you have 10kg pulling force and 100 to 1 compound pulley designed to lift 1 ton weighing item, then to lift 1 ton block for 1m, you would need to pull the rope for 100m.
