Question

A crowbar 27 in. long is pivoted 8 in. from the end. What force must be applied at the long end in order to lift a 600 lb object at the short end?

Answer 1

pivot = 8 in

Balance lenght = 27 in - 8 in = 19 in

Load x load arm = Force x force arm

Replacing:

600 lb * 8 in = F * 19

Solve for F

F = 600 * 8 / 19

F= 252.6 lb
