Determine (a) the forces in the three rods and (b) deflections at

Determine (a) the forces in the three rods and (b) deflections at points B, C, D if element (1) is cooled by 50F. Assume that the rotation of beam AD is small and that all rods are force-free when the system is assembled. (1) 80 in. (2) 50 in. Rigid D 50 in. - 50 in. 50 in. (3) 50 in. A = A2 = A = 1.0 in? E=10 x 10 ksi a = 13 x 10 in/in./F
