A series of shafts is constructed between ends A and D as shown in the figure. Each shaft is made of a material with shear modulus G = 9x106 psi. Segment AC is a hollow tube with an outer diameter of 1.5 in. and a thickness of 1/8 in. Segment CD is a solid shaft with a diameter of 2.0 in. Torques of magnitudes 645 ft-lb and 1200 ft-lb are applied at points A and B, respectively, as shown. (a) Find the reaction at fixed support D. Clearly indicate both the magnitude and the direction (b) Determine the angle of twist at point B, B. Clearly indicate both the magnitude and the direction. (c) Determine the relative angle of twist of the hollow shaft, i.e., PAC. Clearly indicate both the magnitude and the direction. (d) Sketch the shear stress distribution in segments AB and CD. Clearly indicate any important magnitude(s). T = 645 ft-lb A do=1.5 in t=1/8 in 6 in T= 1200 ft-lb B 6 in d=2.0 in 6 in D
