The two cylindrical rod segments are fixed to the rigid walls such that there is a gap of 0.01in between them when T1 = 60°F. 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 aal = 13 x 10-6 in/in °F, Eal = 104 ksi, acu = 9.4 x 10-6 in/in °F, Ecu = 15 x 10° ksi. %3D 0.01in Сopper Aluminum 12in 6in
