Concept explainers
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 gears A and B remove 1 kW and 2 kW, respectively, determine the maximum shear stress in the shaft within regions AB and BC. The shaft is free to turn in its support bearings D and E.

Determine (a) the maximum shear stress in the shaft; and (b) the angle of twist of end D relative to end A. Use G = 83 GPa for steel, and assume that friction at bearing D is negligible.
