A compound shaft drives several pulleys, as shown in Figure P6.18. Segments (1) and (2) of the compound shaft are FI = 28 GPa] tubes, which have an outside diameter of 75 mm and a wall thickness of 3 mm. Segments (3) and (4) are solid 40 mm diameter steel [G = 80 GPa] shafts. The shaft lengths are a = 2.0 m, b = 0.8 m, c = 1.4 m, and d = 1.4 m. The following torques are applied to the pulleys in the directions hollow aluminum [G indicated: T 1050 N-m, TB = 1400 N-m, Tp = 535 N-m, and Te = 185 N-m. 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.

  • A line shaft supporting two pulleys A and B is shown in Figure (below).

    QUESTION 2 A line shaft supporting two pulleys A and B is shown in Figure (below). Power is supplied to the shaft by means of a vertical belt on pulley A, which is then transmitted to pulley B carrying a horizontal belt. The ratio of belt tensions on tight and loose sides is 3:1 and the maximum tension in either belt is limited to 2.7 kN. The maximum belts tension will occur in belt on pulley A due to smaller diameter....
