Problem $6$ at

A $1"$ diameter shaft is driving $2$ pulleys as shown. Calculate and show the stress tensor in point $D,$ located $2"$ from the bearing $E,$ on the top fiber of the shaft $($along the $y-$axis, as seen when looking at the shaft from the motor$).$ Note that the reactions in the bearings are previously calculated and shown below to save the designer's time. Solve in USCS and report stresses as integers.

Please clealy explain the step by step solutions to this problem and include the required FBD AND STRESS ELEMENT showing all stresses at point D$.$
