Moving a wedge to the left

  • #1
the machine part ABC is supported by a frictionless hinge at B and a 10 degree wedge at C. Knowing that the coefficient of static friction is .20 at both surfaces of the wedge, determine (a) the force P required to move the wedge to the left, (b) the components of the corresponding reaction at B.

I have the by component which is found by (-by*10)+(-120*8)=0 and by= 96.0 lb but I am totally lost on how to get bx and the P force

Welcome to the PF.

A sketch of the situation would be most helpful here...
