The machine part ABC is supported by a frictionless hinge at B and a wedge at C. Knowing that the coefficient of static friction is 0.

The machine part ABC is supported by a frictionless hinge at B and a wedge at C. Knowing that the coefficient of static friction is 0.20at both surfaces of the wedge, determine (a) the force P required tomove the wedge to the left, (b) the components of the correspondingreaction at B.
