Question

Include some free body diagrams:

A) Draw the components of the load in each member of the frame shown. Note that BC and AC are both cables. DC is a boom that exerts compression. Use the symbols Ax, Ay and Az for the x, y and z components respectively of force AC. Follow the same manner of representing the components of the other forces,i,e, Bx,By, Bz and Dx, Dy, Dz accordingly.

(B) Set up the equilibrium equation based on summation of moments about AB. Use the symbols indicated in (A). Take the counterclockwise direction as positive. 

(C) Set up the equilibrium equation based on summation of moments about a vertical line passing through B (yB).
