A compound shaft drives three gears, as shown. Segments (1) and (2) of the compound shaft are hollow bronze [G = 6,500 ksi] tubes, which have an outside diameter of 1.75 in. and a wall thickness of 0.1800 in. Segments (3) and (4) are solid
A compound shaft drives three gears, as shown. Segments (1) and (2) of the compound shaft are hollow bronze [G = 6,500 ksi] tubes, which have an outside diameter of 1.75 in. and a wall thickness of 0.1800 in. Segments (3) and (4) are solid 0.95-in.-diameter steel [G = 11,500 ksi] shafts. The shaft lengths are L1 = 50 in., L2 = 16 in., L3 = 18 in., and L4 = 34 in. The torques applied to the shafts have magnitudes of TB = 970 lb·ft, TD = 400 lb·ft, and TE = 130 lb·ft, acting in the directions shown. The bearings shown allow the shaft to turn freely. Using the sign convention presented in Section 6.6., calculate:
(a) the magnitude of the maximum shear stress in the compound shaft.
(b) the rotation angle of flange C with respect to flange A.
(c) the rotation angle of gear E with respect to flange A.
