WebThe coefficient of static friction between the belt and the wheel is μ = 0.3. (Figure 1) Determine the force P that must be applied to the handle of the lever so that the wheel is … WebFriction. The force of static friction does no work on an object at rest and you do no work against this force. Even though you may be pushing hard against an object acted on by the force of static friction, the object is not moving. The displacement is zero and W = 0. You, however, do work against the force of sliding or kinetic friction.
