Rigid beam ABC supports two rods that initially have no strain. If a temperature increase in rod (1) creates a normal strain of 2,545 μin./in. in it, determine the normal strain in rod (2). The initial lengths are a = 10 in., b = 13 in., c = 38 in., and d = 11 in. Assume there is no slack in the connections.
