Question: A 40-lb weight is hung from a lever which rests against a 10 wedge at A and is supported by a frictionless hinge at C.

A 40-lb weight is hung from a lever which rests against a 10° wedge at A and is supported by a frictionless hinge at C. Knowing that the coefficient of static friction is 0.25 at both surfaces of the wedge and that for the position shown the spring is stretched 4 in., determine

(a) The magnitude of the force P for which motion of the wedge is impending,

(b) The components of the corresponding reaction at C.
