A cylindrical rod AB has a length ? = 80 cm and a diameter of ? = 2 cm. The modulus of elasticity is ? = 200 GPa and yield strength is ?? = 300 MPa. The stress-strain diagram of the rod is shown in the left figure. A force ? = 100 kN is applied to the bar and then fully removed (right figure). Determine the permanent set in the rod.

In the shown diagram below, the curved out bar has an axis that is circular (with mean radius r = 12in) and is subjected to the m horizontal forces P = 400lb at the two ends. The cross-section of the bar is a triangular shape with height h and thickness t. If the allowable tensile stress in the bar is 12,000 psi, and height h=1.2 in, what's the minimum thickness tmin that is required?
