As shown in Fig. P-269, there is a gap between the aluminum bar and the rigid slab that is supported by two copper bars. At 10C, A = 0.18 mm. Neglecting the mass of the slab, calculate the stress in each rod when the temperature in the assembly is increased to 95C. For each copper bar, A = 500 mm, E = 120 GPa, and a = 16.8 m/(m C). For the aluminum bar, A = 400 mm, E = 70 GPa, and a = 23.1 m/(mC).
