A rigid bar is supported by two coppe r rods and the gap between the alumi num rod and the bar is 1 mm. If the te mperature for all materials is increas ed by 60 degrees Celsius, will the alu minum rod touch the rigid bar or not? Prove and elaborate your answer. For each copper bar, A = 400 mm^2, E = 120 GPa, and a = 16.8 μm/(m. C). For the aluminum bar, A = 350 mm^2, E = 70 GPa, and a = 2 3.1 μm/(m. C).
