As shown in the figure, there is a gap between the aluminum bar and the rigid slab that is supported by two copper bars. At 10°C, 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 95°C. For each copper bar, A= 500 mm2, E = 120 GPa, and a = 16.8 μµm/(m -°C). For the aluminum bar, A = 400 mm2, E = 70 GPa, and a = 23.1 μm/(m °C). (Practice at Home)
