As shown in Figure MEC - 225, there is a gap between the aluminum bar and the rigid slab that is supported by 2 copper bars. At 10°C, D = 0.18 mm. For each copper bar, A = 50 mm², E = 120 GPa, and a = 16.8 x 10 6/°C. For the aluminum bar, A = 400 mm², E = 70 GPa, and a = 23.1 x 10-6/°C. Compute the stress in the aluminum rod when the temperature is increased to 95°C.
