    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.

    men if in the end of the eight pulley you put anoter pulley to push at both sides you can solve the problem of pull more on one side because you can easily pull both sides, ok you need 2 persons or push one side and hold, go to other side push and hold, but the cargo will wake up more smooth and balanced

    Anyone who off-roads regularly knows how well a snatch block helps. It's small and light enough to keep with you, even if you don't have a winch. Just keep a hi lift jack and you can easily pull yourself out of any situation, in any direction if you can set up pulleys correctly to trees

  18. David Vik

    David Vik5 kun oldin

    Like your videos keep up the good work! FYI a pulley is something that drives a belt or is driven by a belt as the fan and generator on a car are drive by a belt from the engine. In rigging the correct term for the grooved wheel in the block that a rope runs in is a sheave. Yes everyone calls them pulley block, but as the song of my youth said, " Nobody's right if everybody's wrong".

    Thank you for sharing!😊 For the stuck Jeep, I thought you were going to use your TWO snatch blocks. 😆 The second snatch block could be anchored at the Jeep ‘s front anchor. The winch hook then routes back towards the tree, but tied to a DIFFERENT tree. This helps spread the load across two separate trees. I was seriously waiting for the tree to be brought down... 😅

    Well, there's yer problem! Yer tires are bald, you would'na slid off the road in the first place! Good thing you had yer thingy. But thanks for the explanation, I just bought a beefy one off Amazon and didn't know why it worked. Still not sure how it works, but now I know what I don't know. I believe this could be explained using leverage of logs to exemplify distance input vs work done with varying fulcrum points. That would help to explain doubling the length of rope pulled to distance of load moved. Just sayin- Do know one thing 'tho, I'm gonna buy at least 2 more.

    Great video! We had an engine to remove and install in a tractor. Had a A- frame but the Come along wasn't strong enough to lift the engine block. Someone said let's use a cheater pipe on the come along. I didn't agree. We would exceed its rating. A cup of Coffey and starring at it for a half hour and still nothing. Called a friend. Went by his house and he hands me several pulls and some heavy rope. Four pulls and the come along worked with no strain. I think we could have pulled it by hand with a few more pulls. Now pulleys are part of my tool box and have used them many times. Yes, you can learn a lot from the past.

    The FBD method of explaining this never sticks. In one ear, and out the other. You should learn it, though, but you fundamentally need more analysis to do anything with it. FBD are useful to size individual components in your snatch block, for example. You don't need them at the macro level, which is what we are dealing with here. The technique that is MUCH more useful is the black box approach. You can use this technique in all sorts of problems, and is often used as a 'double check', to check your work. It's that fast. It's the first law of thermodynamics, ie energy must be conserved. For simplicity we will ignore inefficiencies, as they are tiny in comparison. If you move a machine's inbut 2 feet, and the output responds by moving 1 foot, you have a 2:1 mechanical advantage. Power is force over a distance. The power going in is Force * 2 feet. The power coming out must be Force #2 over 1 feet. Power in = Power out F1 x 2' = F2 x 1' F2 = 2 x F1.
