A compound shaft drives three gears, as shown. Segments (1) and (2) of the compound shaft are hollow bronze [C-6,500 ksi] tubes, which have an outside diameter of 1.85 in. and a wall thickness of 0.1975 in. Segments (3) and (4) are solid 1.05-in.-diameter steel [G- 11,500 ksi] shafts. The shaft lengths are / ₁- 66 in., 1 2 – 12 in., 13 - 20 in., and 14-31 in. The forques applied to the shafts have magnitudes of TB - 900 lb-ft, Tp-460 lb-ft, and TË - 170 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 with respect to flange A. (c) the rotation angle of gear with respect to flange A. TB Tp (1) TE (2) (3) (4) C L₂ Answer: (a) Tmax (b) c/A= (C) PE/A- L1 B L2 psi rad rad D La E
