  • 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.

    • I've got a video idea for you. I've been a heavy equipment operator since I was a literal child, outside of my time in the USAF as a crew chief. I've always wondered what the data would look like if there were sensors on the control levers to read inputs, as well as sensors on the machine to show how fast/slow, to what degree/modulation the input had on the machines movement. Kinda like a "humans are awesome" video, where it highlights what type of aquired skill it takes to get the machine to move with such precision. Etc etc.

  • Hey Destin, not sure how to reach you other than comments, but i was wondering if you could do a video on the calculation for something like this video YGi0G4E5bCk ***** In Short, they are making an ice carousel, and i was wondering how the calculations would be done to determine the serviceable lifespan of a carousel, given it's parameters, thickness, diameter, water temperature, outside temperature, density, rotation speed, etc. to see what it's carrying capacity would support, and the safe amount of serviceable life a carousel would have... Thanks

  • This work multiplication is also what makes a trucker's hitch so good at ratcheting up tension. You don't actually use a pulley- you just use have direct rope-on-rope friction by putting the bitter end through the bight of the slipped half hitch- but it's the exact same principle. I suppose technically you never *need* a pulley, because you can always just tie one rope through the other, but pulleys are always helpful because: 1. Any knot in a rope will weaken the rope, and 2. Pulleys reduce friction when you're pulling on the rope. Which means you don't have to pull as hard, the rope lasts longer, and just generally everything's way less likely to snap in your face or tighten irrevocably.
