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.

The extra snatch block at 7:30 does nothing for mechanical advantage. You just redirected the direction of your pulling force. Still great information!

the short answer is you use a series of rotating levers to change the ratio of pull to travel distance - that is the actual answer

Idk why but I would love to see more of those super fast "Snatch block!" Type edits like at 12:02 in future videos (maybe minus the "when it doesn't work" part). There's something hilariously efficient about it and I can totally see a whole series of super short "how to use a X" type videos all built around exactly that style of ridiculously fast and aggressive tutorials. Not to mention those would make for killer tiktok videos since people would probably have to watch them a few times to really get it and the tiktok algo eats rewatches for breakfast. Also, just watching that "Snatch block!" Scene at 2x speed is even better cuz it just 2xes the already ridiculous efficiency and aggression xD

Ok, so my understanding is that the mechanical advantage of a fixed pulley is 1:1, so how would the fixed snatch block on the tree give you any mechanical advantage to pull the hero out?

Charles Turner Před 4 dny
Ok, I'm going to probs sound stupid but, bare with me. If pulleys can be used to increase the force through a medium such as rope, then can that be used as an advantage to get power? And yes I k wo there is not such thing as free power, but I just cant get my head around it.

I can't wrap my head around it, to me it looks like you're getting extra energy from nothing
Katai
Katai Před 4 dny
Not exactly from nothing, since you have to pull farther the easier it gets - so you kind of trade weight for distance. Or possibly better to say it's breaking up that one big load of work into many more smaller ones? I'm not an expert either :)
1Maklak
1Maklak Před 5 dny
There are two pieces of physics to understand blocks and tackles: 1) Tension (force) on both sides of a block must be equal, otherwise it would equalize. 2) Since W = F * s (where W - work, F - force, s - distance), you can do the same work by trading force for distance. For example with one block attached to the thing you're pulling and one end of rope anchored, you're using half the force, but have to pull twice as much rope to move the thing the same distance.

How is that this phenomenon can’t somehow be used to generate energy?.. like use 2 lbs of energy to lift 10 lbs of force that then converts to energy?..
Brandon
Brandon Před 3 dny
@ASI ahhh. The distance you pull the rope is increasing relative to the distance the weight moves?.. makes sense..
ASI
ASI Před 5 dny
Because you can't create new energy. If the force is increasing its because the distance that force is applied over is decreasing

LARRY CURRIER
LARRY CURRIER Před 5 dny
easy explanation, 1 pulley means equal weight, 2 pulleys divided by 2 so half the weight. Three Pulleys means you divide in half the amount of force from the last loaded pulley. Every time you add a pulley you divide by half the last loaded pulley. With enough pulleys a two-year-old could pick up a freight train. the other thing to remember is every time you add a pulley you're going to pull twice as much rope then you did in the prior to move something the same distance

I just showed this video to my husband, who, poor guy, had the fun experience of winching his truck up our driveway during the great Texas deep freeze in Feb 2021, when it was a solid sheet of ice. Y'know what he needed to make it a heck of a lot easier? Snatch blocks!
towtruckAJ
towtruckAJ Před 5 dny
Chances are he was better off with the single line if he had a strong enough winch, the resistance of a vehicle simply slipping on ice is not all that much and a 2:1 snatch block setup would take twice the line to cover the same distance so over 100 feet of line you would make it 50 feet, so if your single line handled it that was likely the best bet as you would get the full distance of your line at each pull.
