Problem 4.72 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 = 60°F. Each rod has a diameter of 1.95 in. Take Qal = 13(10-6)/°F, Eal = 10(10³) ksi, (oy)al = 40 ksi, acu = 9.4(106)/°F, (Oy) cu = 50 ksi, and Ecu = 15(10³) ksi. Figure . 0.01 in.
