And also the fact that the other mass is pulling you up at 2/3 the force of gravity pulling you down in the example he provided. So you would accelerate WAY slower than falling speed.
Thats really cool, I never knew pulley systems actually take a bunch of weight off, I thought they were just to get from point A to point B with a counter weight adding them extra pulleys really cuts the weight. This was surprisingly really educational
Great Video, we actually did something simular to this, only using 1 pulley system to lift our Engineering teacher to the roof of the building using only 1 hand! It’s amazing how Pulleys work. I think it would be cool to continue to do lessons explaining Engineering and using Simple machines and how they make our lives easier. Lots of educational value here! Thanks!
Bad choice. Grown man with what looks like nothing higher than middle school education trying to teach kids on the internet something that kinda resembles science.
dude! thank you! I've been meaning to make cerebral time to learn pulleys. I've worked as a stage hand, and ground rigger, so i understand simple pulleys, and I understand block and tackle, and load reduction off a series of similar pullies, but knew nothing of the combination, and by placing the pulley in different locations you get different work to lift lad results.
10:30 No.. you would not hit the ground by the full speed of gravity. Because you need to over come inersia. So if you say are 100kg Heavy. The pully breakes you with 75 kg, the gravity will pull you down with 25 kg, but your mass is still 100kg. This would make the speed 1/ 4 of gravity. Actually it would be even less. Because the pully is also lifting the weight on the other side with 25 kg and if that weight is 150kg but hat half speed, that give is a effective mass of 75kg: The actuall moving speed is (100+75)/25)= 1/7 of gravity
Hey Nate can you try my idea of homemade fireworks Inflate a balloon with hydrogen tie it to a short length of string and before you let the balloon go light the string on fire so it will act as a fuse and the balloon will explode as it rises Like so TKOR can see
I had a sort of pully on my treehouse. It wasn't an atuall pully, but a rope slung over a branch. What I found fascinating is that when you pull yourself up this way, by putting a loop at the the bottom for your foot... The effort to pull is lessened more than you'd think. When you're standing with your foot in the loop at the end, 100% of your weight is there. Then when you pull you're not just lifting your total weight, you're also taking weight off your foot, because you're pulling yourself up at the same time. The net effect is really fascinating.
Wow! Being a carpenter I have wanted to build an elevator with wood. This is the design I envisioned! I live on the third floor. I'm gettin' ole... Also it will be useful to lift building materials. Buenisimo! Got me!
Dude You Need To Tie A Helium Balloon To A Sulfer Hexoflouride Balloon And See If It Floats In Mid Air Because The Helium Can Lift The Sulfer Hexoflouride And The Sulf Hexoflouride Keeps The Helium From Flying Away! Please Like This So He Sees! This Has Never Been Done Btw Revolutionary!!!
i dont understand pls explain more detailed dont worry about confusing me tho cuz i know what quantum physics are yet i dont know how balloons work... dont ask lol
It would not float in mid air. Assuming the balloons were the same size the SF6 balloon would be like a weight pulling down on the He balloon. Lighter than air balloons float because the heavier air falls around the balloon, forcing it upward.
10:25 : thats wrong! 1. "speed of gravity" is a pretty bad term for that. Its more like the speed you end up on the ground after getting accelerated by gravitational force. 2. The gravitational force is pulling you downwards sure, but you have to take the force of the counterweight in to account, which is going upwards. Think about a counterweight, that is (in your configuration twice) as heavy as you are: You wouldn't move at all, because upwards force is just as big as downwards force.
He is wrong, but you are also wrong as the weights are 7.5 lb and 10lb. But yes everything else you said is correct and it pains me to see him misunderstand the concept of gravity. You have to take the net force acting on the body moving down and divide it by it's weight to get it's acceleration. Thus, 7.5 lbs down left*2 +10lbs down right = 5 lbs of force down left. The net acceleration is then the mass of the 7.5 lbf/5 lbf. Or roughly 2/3 of the normal acceleration of gravity. I believe, but did not actually do the math of the mass to solve for acceleration.
I dont know where i got wrong though. Didn't say anything about the weights he used. But i think you are wrong now. :p Down weight = 7.5 lb, Up weight = 5 lb (10 lb /2) So net weight left 2.5 lb (down). Thats 1/3 of 7.5 lb. So it should be only 1/3 of gravitational acceleration, right?
@@alexu.9294 I agree with that, I just noticed in one line you said the counterweight was twice as heavy and was restating that it's actually 4/3 as heavy. Besides that I believe we are in agreement!
This was one of the best videos you've made! It would be cool to see a series on these classical machines and cool ways to implement them at home. Also agree with everyone here saying you should make the full scale version! It would be sooooo cool!
Our tree house does! One for hosting things up and another for the door, there is an anchor on one end that counterweights the big rectangular door that swings upward.
I'd love to see that series of videos. It will take more than one for the build. My only fear is that Nate would have so much fun in his new tree house that he might never come down!
You could build an elevator basket with some sort of air cushion or a spring at the bottom, that way if you'll soften the landing. Also maybe you could put a friction break on the static pulleys, just permanently applying a bit of friction to slow things down.
Great video, really fun to watch! Just a little thingy, I think a few time you misuse 'lift' instead of 'hold', which could bring confusion to some listeners. Since if you 'lift' (which is to create an upward movement) 4.5 kg with a moving pulley, you're gonna need more than 2.25kg of 'weight' because you need to unbalance the 'weight' equilibrium. But if you want to 'hold' (which is to maintain in equilibrium the two weights) then 2.25 kg should do it.
I would love to see this elevator made into a full scale. What would be even cooler is if you could make a tree house and see how many cool extra functions you could at to it
you could use a bucket as a counterweight. to get up the bucket must be filled with a bit more water than what is needed to balance the weight, to get down you would remove just a bit of water and slowly move down. all with one system of pulleys.
A wheel and axel is a type of lever, and so is a block and tackle. There are THREE Simple Machines: the Lever, the Inclined Plane, and the Hydraulic Ram. Everything else is an embodiment, or combination, of one or more of these THREE. This includes the Torque Accelerator, which is a type of Lever which has a Moving Fulcrum.
I'd love to see a full scale of this, I'm all for seeing mechanics overcome electricity. I'm really tempted to try this, just didn't exactly know how it'd be done.

In the full-scale system, have a mechanism that stops moment if the weight suddenly falls to the ground (like a seat belt). This would prevent the large weight falling on someone on the ground if the rope was let go.

Thanks for the metric measurements 👍🏼

Max Blockley yes Australia m8
FYI correction, if the pulley are frictionless you would NOT accelerate at falling speed due to the other mass momentum gain.
glad you pointed that out. you beat me to it
And also the fact that the other mass is pulling you up at 2/3 the force of gravity pulling you down in the example he provided. So you would accelerate WAY slower than falling speed.
@@davidharmeyer3093 Yes I believe the EOM would be m(double dot) +T = m(double dot) + 2T, which results in the 2/3 you mentioned above.

Lighter than air balloons float because the heavier air falls around the balloon, forcing it upward.
not revolutionary they aren't exactly oposite
This is a GREAT video. It demonstrates 2 important concepts.
1) Work = force * distance.
2) Conservation of energy
Yeah but he misinterpreted F=ma

In the full-scale system, have a mechanism that stops moment if the weight suddenly falls to the ground (like a seat belt). This would prevent the large weight falling on someone on the ground if the rope was let go.
