A winch pulls a 500# cart up a hill, as shown. The main shaft of the winch is shown below, simply supported by bearings at A and C. The winch uses a 6"diameter pulley (B) and torque is applied at the end of the shaft to pull the cart. Determine the minimum shaft diameter based on the Maximum Shear Stress criterion using on a yield strength of 50ksi and a design factor of 2.0. 12"
