You use the lever below to lift a box.
If you apply a force of 220 N to the lever, how much force is applied to lift the
crate?
A. 286 N
B. 220 N
C. 169 N
D. 455 N
Explication: If the perpendicular distance from the point of application of the force to the fulcrum is x metres and the perpendicular distance from the crate to the fulcrum is y metres, then the force applied on the crate is 220*x/y N.
