3. An 8-m steel shaft rotating at 180 rpm has 7OKW applied at a gear that is 3.0m from the left end where another 60kW are applied. The shaft in between the two gears is solid with diameter=D40mm. At the right end, 80kW are removed and another 50kW leaves the shaft at 3.60m from the right end. The shaft is hollow between these gears with outside diameter=80mm and inside diameter=70mm. The shaft between the 70kW and 50kW is hollow with outside diameter=60mm and inside diameter=50mm (a) Find the stresses in each shaft. (b) Determine the angle (in radians) by which one end of the shaft lags behind the other end. Use G=83GPa. A
