Question

You're trying to lift a 298 pound object with a first class lever. You're pushing down on one side of the lever 9ft from the fulcrum, and the object is on the other side 2 ft from the fulcrum. Assuming no friction (balanced moments), how much force do you have to apply to lift the object?

Answer 1

66.2 lbf

Step-by-step explanation:

∑τ = Iα

F (9 ft) + (298 lbf) (-2 ft) = 0

F = 66.2 lbf
