The hollow steel shaft DF has an outer diameter of 25 mm and inner diameter of 15 mm is supported by smooth bearings at D and E as shown in Figure 4. It is used to transmit 12 kw from motor F to gears A, B, and C operating at a speed of 50 rev/s. If gears A, B, and C reduce 3 kw,4 kW, and 5 kW respectively, determine i. the maximum shear stress in the shaft at regions CF and BC ii. the minimum diameter of the shaft if a solid shaft is used. 5kW 12 kW 3 kW 4kW C EF Figure 4 Shaft assembly driven by a motor
