3. A 4 inch diameter solid circular shaft has a V-belt pulley attached to one end and is supported as shown below. The combined pulley weight and belt pull is 1000 lbs. Determine the magnitude and location of the:
(a) maximum horizontal shear stress
(b) maximum bending stress
Neglect the shaft weight.
Attachment has the drawing
This solution determines the magnitude and location of maximum horizontal shear stress and the maximum bending while neglecting the shaft weight.
