Problem 5.50 - Thermal Deformation

Problem Statement

The axial stress in a solid circular bar between two fixed walls is 30 ksi. Find the temperature change necessary to relieve the stress. Assume L = 30 in., E = 29,000 ksi, and α = 6.5 x 10-6 / °F.

A solid circular bar is between two fixed walls with length L.
