Question

A steel cylinder is enclosed in a bronze sleeve, both simultaneously support a vertical compressive load of 250 kN which is applied to the assembly through a horizontal bearing plate. The lengths of the cylinder and the sleeve are equal. Compute the temperature change that will cause a zero load in the steel. Also, determine the temperature change that will cause a zero load in bronze. For the steel cylinder, the area is 7,200 sq mm, E is 200 GPa, and alpha is 11.7 micro meter per meter degree celsius. For the bronze sleeve, the area is 12,000 sq mm, E is 83 GPa, and alpha is 19 micro meter per meter degree celsius.
