Chapter 4 Problem 4.71 The two cylindrical rod segments shown in the figure below (Figure 1) are fixed to the rigid walls such that there is a gap of 0.01 in between them when T₁ = 80°F. Each rod has a diameter of 1.7 in. Take aal = 13(106)/°F. El=10(10³) ksi, (oy)al = 40 ksi, acu = 9.4(106)/°F. (ay)cu = 50 ksi, and Ecu = 15(10³) ksi. Figure 0,01 in.. Copper 12 in Aluminum -6 in. 1 of 1
