A steel 0.75-in diameter shaft (G= 12,000 ksi) is subjected to the following torques in lb-ft: TA = 10; TB = 30; TC = 70; TD = 50. The directions of the applied torques are indicated in the figure The bearings shown allow the shaft to turn freely. The length of each segment is equal to 38 in. (a) Plot a torque diagram showing the internal torque in segments (1), (2) and (3) of the shaft. Show the FBD of each segment using a double-headed arrow to represent each torgue. Determine (b) the maximum shear stress magnitude in the shaft. (c) the rotation angle of pulley C with respect to pulley A.
