A thin-walled cylinder is made of material that has a Young's modulus of 70 GPa, a Poisson's ratio of 0.33, and a coefficient of thermal expansion of 24×10−6 /?C. It has an average radius of 100 mm, and a wall thickness of 2.0 mm. The cylinder is constrained between two rigid walls, so that it can't expand in the axial direction. It is pressurized to an internal pressure of 1.5 MPa, and then the temperature is raised. What is the maximum temperature rise that can occur without the maximum shear stress in the cylinder exceeding 75 MPa?
