Question: The figure shows an endless-belt conveyor drive roll. The roll has a diameter of 6 in and is driven at 5 rev/min by a geared-motor

The figure shows an endless-belt conveyor drive roll. The roll has a diameter of 6 in and is driven at 5 rev/min by a geared-motor source rated at 1 hp. Determine a suitable shaft diameter dC for an allowable torsional stress of 14 kpsi.
(a) What would be the stress in the shaft you have sized if the motor starting torque is twice the running torque?

(b) Is bending stress likely to be a problem? What is the effect of different roll lengths B on bending?
