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.

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

Mechanical Sympathy
Also the whole scene staging is kind of low tier. Like “omg this random pulley shows up to help me save the day with //STATCHBLOCKtm\\ !!” Come on. Also i dont know why ur calling pulleys snatchblocks. They are pulleys. No need for some fancy clickbait term like snatchblock. Unless you want to lure in jealous fathers who want to buy bulletproof chastity underwear for their daughters.

Great stuff! As a young civil engineer, working for a bridge construction company, one of my regular tasks was designing critical lift plans. Basically, beam erection plans. They included selecting the right crane(s), and the required “rigging” (i.e. cable size, number of parts in the block and tackle, lifting clamps, etc. Your video brings back lots of great memories.

That is why you don't need a 10,000 pounds winch to pull 6,000 pounds truck, you can do it with a 3,000 pounds winch and 2 snatch blocks, but remember always that each snatch block doubles the force, but multiplies the time... The force luke!

I knew someone years ago who lived in an upstairs apartment and used a pulley system to bring stuff upstairs in a pan attached to the pulley. There was also someone else I knew who lived alone in his senior years who used a pulley to get a couch into his attic all by himself. As for that jeep, when you cut off the engine, you’re really supposed to put it in neutral to move the car without power

I don't see how adding the second block when pulling the truck on the trailer gave anymore mechanical advantage, it seems like it only changed the direction you were pulling from with traffic to against it. This seems like the same set up from the first example you did with your kids, which you said was a 2:1 system.

Your jeep example was a fail. Let me explain why. Go to back to the ladder and cinder block example, and pretend your kids are the winch. On Example A, you have a single pulley and 3 point of contact. The winch, the pulley, and the blocks. You stated you are simply redirecting the force, which is true. On Example B, You have 2 pulleys, and 4 points of contact. The winch, the pulley, the snatch block, and the anchor back at the top. Now let's go back to the jeep. You only have 3 point of contact. The winch, the snatch block, and the jeep shackle. All you did was redirect the force so the winch could be anchored onto the jeep. The jeep still moved because it was the object of least resistance. What you forgot to do was add the fourth point of contact that would have given you your mechanical advantage. Had you put a snatch block on the shackle of the jeep, and anchored winch hook back to the tree, you would have gotten your advantage.

I thought I recognised Jeremy from somewhere! I came here because Steve Mould had clips of you "chanting" "SNATCH BLOCK!" in his pulley video and I had to find out what the enthusiasm was all about.... and (oh boy) did I find enthusiasm! .... you like your pulleys! ;) I remember Story Musgrave (on TV) taking about a "come along" I was hoping there'd be one of those in Chris Hatfield's tool box too... so I could finally see what it is.

First thing I thought of when you were lifting the cinderblocks was the Pyramids of Giza. Maybe advanced pulley systems existed long before Archimedes.

Does the pulley size correlate to potwntial power and how would assending or descending pulley size affect overall draw?
Daniel Combs
Daniel Combs 13 dager siden
Pulley size only comes into play as related to the stiffness of the rope (thicker ropes need larger radii of curvature). Does not affect power output/mechanical advantage

Thanks for the upload...... I’m in the curious but confused club regarding pulleys ...... during lockdown I installed a new 80’ clothes line with a winder mechanism. It works okay with 3 single pulleys, 1 directly above the winder & the other 2 pulleys secured to large tree branch’s to complete the loop . Would replacing the single pulley directly above the winder give me mechanical advantage or is needed between the 2 trees ? Appreciate your thoughts & promise I won’t take the credit! Ha ha ha

Brilliant, I love pulleys too! Also how about some love for differential pulleys? I 3D printed a coat rack with hoist between my stairs, I was hoping I could just use it to lift my coats into the unused space between the staircase but alas I misjudged my ratios/how heavy coats are, so it's just static now.
