A bunch of light rotations with your hand

>Work = Force x Displacement
Which of Newton's laws of motion is that?

the inclined plane

>big boy brain doesn't grasp that basic mechanics includes energy relationships

I understand how it works, but that actually does sound crazy when you word it like that

Somebody explain to me why the force pushing down on the jack doesn't cause the thing to rotate and get lower.

Don't pretend a question is easy unless you have the ability to answer it correctly. You're not fooling anyone.

You're in good company. Archimedes said "Give me a place to stand and with a lever I will move the whole world." Mechanical advantage is weird.

I believe it boils down to friction. The incline is so slight from the round gear's perspective that it is pushing more against the worm gear than down along an inclined plane. I don't know if there's a clean mathematical model for this.

On the fixed end there's a rachet (or something that works like a rachet) you can release when you want it to lower

op you are a faggot read until you cure
