4. The rigid slab is supported by two identical copper rods as shown. The copper rod has an area of 500 mm? with a = 16.8 µm/ ( m°C ) and E = 120 GPa. There is a gap of 0.18 mm between the slab and the aluminum rod. The aluminum rod has an area of 400 mm? with a = 23.1 um/ ( m°C ) and E = 70 GPa. Compute the stress developed in each rod when the temperature is raised to 85°C. Assume that the weight of the slab is negligible. Aluminum Copper -750 mm

![4. The rigid slab is supported by two identical copper rods as shown. The copper rod has an area of 500
mm? with a = 16.8 µm/ ( m°C ) and E = 120 GPa. There is a gap of 0.18 mm between the slab and the
aluminum rod. The aluminum rod has an area of 400 mm? with a = 23.1 µm/ ( m°C ) and E = 70 GPa.
Compute the stress developed in each rod when the temperature is raised to 85°C. Assume that the
weight of the slab is negligible.
