Question

Please prove the answer to this exercise, the answer is already given, written in bold. Thank you

The shaft shown below is the input shaft of a worm gear drive. The V-belt sheave receives
7.5 hp from directly downward. The worm rotates at 1750 rpm and has a pitch diameter of
2.000 in. The tangential, radial, and axial forces are shown in the figure. The worm is to be
machined integrally with the shaft, and it has a root diameter of 1.614 in. Determine (a) the
forces on sheave B and (b) the maximum resultant moment.
