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"

What is the maximum power that can be delivered by a hollow propeller shaft (outside diameter 50 mm, inside diameter 40 mm, and shear modulus of elasticity 80 GPa) turning at 600 rpm if the allowable shear stress is 100 MPa and the allowable rate of twist is 3.0°/m?

A solid circular shaft AB of diameter d is fixed against rotation at both ends (sec figure), A circular disk is attached to the shaft at the location shown. What is the largest permissible angle of rotation 0max of the disk if the allowable shear stress in the shaft is Tallow? [Assume that a >b. Also, use Eqs. (3-50a and b) of Example 3-9 to obtain the reactive torques.]

Repeat Problem 11.2-3 assuming that R= 10 kN · m/rad and L = 2 m.
