Question
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. The temperature in the assembly is
increased to 95'C. Neglect the mass of the slab.
For each copper bar, A = 500 mm², E = 120 GPa, and acopper = 16.8 x 10° m/(m.'C).
For Aluminum bar, A = 400 mm', E = 70 GPa, and aaluminum = 23.1 x 10°m /(m.'C).
