Rigid beam ABC supports two rods that initially have no strain. If a temperature increase in rod (1) creates a normal strain of 3,045 μin./in. in it, determine the normal strain in rod (2). The initial lengths are a = 8 in., b = 15 in., c = 34 in., and d = 9 in. Assume there is no slack in the connections.

Axial loads are applied with rigid bearing plates to the solid cylindrical rods.
