The shaft shown in the figure has a diameter of 23.3 mm and is supported by smooth journal bearings at A and B. Due to the transmission of power to and from the shaft, the belts on the pulleys are subjected to the tensions shown. a) If the reaction forces at A and B are calculated as: (RA)y 475 N; (RA)z=-150 N; (RB)y = 475 N; (RB)z = 650 N, draw the free body diagram of the shaft and clearly show the labels and directions of all loads applied to the shaft. b) Draw the shear force, bending moment, and torque diagrams for all applicable planes. c) Calculate the maximum principal stresses and the maximum shear stress in the shaft. 0.250 m Y 550 N 0.250 m 0.050 m 300 N 200 N 400 N 0.150 m D 0.075 m
