The two cylindrical rod segments are fixed to the rigid walls such that there is a gap of 0.01in between them when T1 = 60F. Determine the larger temperature T2 required in order to just close the gap without producing stresses in the rods? Each rod has a diameter of 1.25in. Take a = 13 x 10 in/in F, Ea = 10* ksi, aa = 9.4 x 10 in/in F, Eu = 15 x 10 ksi. (8) 0.01in - Copper Aluminum 12in 6in
