A short, cantilevered round peg is 40 mm in diameter and extends 10 mm from the wall. It is loaded, as shown, with a force F = 50 kN applied at the tip in the negative z direction, and a torque T= 800 N-m. The cross-section at the wall is also shown, with points of interest A, B, and C. This is made from AISI 1040 cold-drawn steel. Evaluate the state of stress at points A, B, and C, determine the critical case, and evaluate the minimum factor of safety based on (a) the maximum-shear-stress theory. (b) the distortion-energy theory. 10 mm F A B C Cross section at the wall
