Determine the absolute maximum shear stress developed in the shaft in Problem.

Problem

The solid steel shaft DF has a diameter of 25 mm and is supported by smooth bearings at D and E. It is coupled to a motor at F, which delivers 12 kW of power to the shaft while it is turning at 50 rev/s. If gears A, F, and C remove 3 kW. 4 kW. 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
