Question

The shaft shown below is transmitting 150 hp at o- 1030 steel, quenched and provide simple supports. Gears mounted to the shaft create the transverse forces shown. For L-24 in, do-2.5 in, - 0.125 in, Fi-800 lb, and factor of safety of the shaft with respect to yielding. Use both the von Mises shear stress criteria and compare the results of the two. Recall the power, torque, and spee rotating shaft are related through P- oT, where Pis the power, o t torque, all in consistent units. 900 rev/min. The shaft is made of AISI tempered at 1000 deg F. There are two bearings, one at each end that Fi and F2 as F2 1600 lb, determine the and maximum in a the angular velocity, and T the SECTION A-A (ENLARGED)
