5. The solid steel shaft DF has a diameter of 25 mm and supported by smooth bearings at D
and E. It is coupled to a motor at F, which delivers 12kW of power to the shaft while it is
turning at 50rev/s. If gears A, B, and C remove 3 kW, 4kW, and 5 kW respectively,
determine the maximum shear stress developed in the shaft within regions CF and BC .
The shaft is free to turn in its support bearings D and E.
