A copper rod with 0.15 cm diameter is enclosed by a steel tube that has an outside diameter of 0.3 cm and an internal diameter of 0.2 cm. The assembly is fixed at each end. Determine the stresses in the rod and tube if the temperature is at 220oC; at 10oC, there is no longitudinal stress. Based on laboratory results for steel, E = 2.1 x 105 N/mm2, a = 11x10-6/oC, and for copper, E = 1 x 105 N/mm2, a = 18x10-6/oC

Question

A copper rod with 0.15 cm diameter is enclosed by a steel tube that has an outside
diameter of 0.3 cm and an internal diameter of 0.2 cm. The assembly is fixed at each end.
Determine the stresses in the rod and tube if the temperature is at 220oC; at 10oC, there
is no longitudinal stress. Based on laboratory results for steel, E = 2.1 x 105 N/mm2, a =
11x10-6/oC, and for copper, E = 1 x 105 N/mm2, a = 18x10-6/oC
