Does anyone know what the lever law is (not just that it exists but what it actually states)? I''ve looked for it and I can''t find the thing, and I''m needing it soon so any help is greatly appreciated. Thanks.

Well, it runs over the torque formula:
M = F * l

where F is the force and l is the distance between the exertion point and the hinge.

So, for example, you need to know the force (F₂) on the other side of the lever at position l₂ and F₁ is excerted at l₁.

F₁ * l₁ = F₂ * l₂

So:

F₂ = (F₁ * l₁)/l₂
