Part 1 of 2
Required information
A short cantilevered round peg made from AISI 1,020 cold-drawn steel is 40 mm in diameter and extends 10 mm from the
wall. It is loaded, as shown, with a force $F = 50 \text{ kN}$ applied at the tip in the negative $z$ direction and a torque
$T = 800 \text{ N} \cdot \text{m}$. The cross section at the wall is also shown, with points of interest A, B, and C.

Evaluate the state of stress at points A, B, and C, determine the critical case, and evaluate the minimum factor of safety based on the
maximum-shear-stress theory. (Round the final answer to three decimal places.)
The minimum factor of safety is
