1. The problem statement, all variables and given/known data 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. 2. Relevant equations 3. 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.
