Once this concept is grasped, you can tie shit to your car from ikea using a simple rope, instead of noob straps, and it'll be there when you get home.

that only happens when you add them together in a block and tackle arrangement

Ikea makes cars? The magnetic hood latch would make for an exciting ride.Once this concept is grasped, you can tie shit to your car from ikea using a simple rope, instead of noob straps, and it'll be there when you get home.
kids, don't do drugs
or you will forget how pulleys work

The massive counterweights help. The leverage is probably through gears though. But I'm sure some mechanical advantage comes from pulleys.It's like a fulcrum but round. The longer the fulcrum, the more you can lift.
Yeah, it's been a long ass time since I was in advanced physics, but I believe it's work= force x length. Or at least in terms of fulcrums. Work can be applied to electricity or temperatures and shit as well. Like a peltier device.
I have to wonder if elevators use the power of pulleys or just straight cable on motor?
The simplest ELI5 of how pulley's work is trading off speed for power.
An extremely simplified example.
1. You pull the pulley at 5 mph with little effort.
2. The heavy weight at the end of the pulley goes up at 1 mph.
This is how gearing works.
1. You spin your feet on a pedal at 60 rpm with little effort
2. The wheel spins at 10 rpm but easily climb a hill.
You can go the other way too, trade off power for speed
1. You spin your feet on a pedal at 10 rpm but with lot's of force.
2. The wheel spins at 60 rpm giving you a lot of speed.
Sorry about this guys.
Where the hell's Mayne?!why apologize? without your dumb threads there would be next-to-nothing going on around here.
You also don't get the same lift in thinner air so you need mo power to not fall.It's analogous to that of flight. When you are way up there in the air the air is much thinner. Therefore you don't have to use that much power to push yourself through the atmosphere and you save on fuel at the same time. Well, winds can be a factor. The coefficient of friction still applies.
You don't need more power, you just need to go faster. Which is easier because of the thinner air.You also don't get the same lift in thinner air so you need mo power to not fall.
Don't worry I'll be backwhy apologize? without your dumb threads there would be next-to-nothing going on around here.

Just checked. He's not there!If he was up your ass with a ham sandwich you'd know it!
