The solid steel shaft AC has a diameter of 25 mm and is supported by smooth bearings at D and E. it is coupled to a motor at C, which delivers 3 kW of power to the shaft while it is turning at 50 rev/s. If gear A and B remove 1 kW and 2 kW, respectively, determine the maximum shear stress developed in the shaft within regions AB and BC. The shaft is free to turn in its support bearings D and E.The solid steel shaft AC has a diameter of 25 mm and is supported by smooth bearings at D and E. it is coupled to a motor at C, which delivers 3 kW of power to the shaft while it is turning at 50 rev/s....
