Determine max notmal stress, average shearing stress and bearing stres

Homework Statement

The position of piston Cd is locked and force P = 350lb is applied as shown. The diameter of all pins and bolts is 3/8 in., member BCE has a thickness of 1/4 in., and member Ef has a width of 1 in. adn thickness 1/4 in.

Homework Equations

The Attempt at a Solution

Unless I'm much mistaken, this is mostly a statics problem.

Initially I tried drawing a FBD of member BCE with my x-axis along the bar starting at E and going right, and then I had my y-axis perpendicular to this (perpendicular to the bar BCE) pointin upwards.

But this seems to give me 6 unknown forces, Bc, By, Cx, Cy, Ex and Ey.

Any advice would be appreciated.

P is the only force applied at point B. The components of P can be determined from the angle relationships shown on the diagram. You are given the magnitude of P (350 lbs). You should be able to write equations of equilibrium about point C.
