Space frame ABC is clamped at A, except it is free to rotate at A about the x and y axes. Cables DC and EC support the frame at C. Force P_y = − 50 l_b is applied at the mid-span of AB, and a concentrated moment Mx = − 20 in.− l_b acts at joint B.

(a) Find reactions at support A.

(b) Find cable tension forces.
