P6.19 A compound shaft drives several pulleys, as shown in Figure P6.19. Segments (1) and (2) of the compound shaft are hol- low aluminum [G = 4,000 ksi] tubes, which have an outside diam- eter of 3.00 in. and a wall thickness of 0.125 in. Segments (3) and (4) are solid 1.50-in.-diameter steel [G = 12,000 ksi] shafts. The bearings shown allow the shaft to turn freely. Calculate (a) the maximum shear stress in the compound shaft. (b) the rotation angle of flange C with respect to pulley A. (c) the rotation angle of pulley E with respect to pulley A.
