Question

The drive roller rotates on a 2.000-inchdiameter shaft on two outboard bearings attached to the frame of the conveyor system. A2-inch shaft extends beyond the bearinga total of 6.00 inchesto allow a drive mechanism. To drive this shaft, a pulley, orsprocket, or gear must be attached to the end of the shaft.  Assuming thedrive component (gear, sprocket, or pulley) is permitted a diameter ofno more than15 inchesto allow guarding and clearance.Find all forces, torques,andmoments on the shaft. Designand analyze a square keyto drive the shaftand showa key is or is notsufficient to transmit the torque generated.
