Question
The motor A delivers 7500 kW to the shaft at 3600 rev/min, of which 2500 kW is removed by
gear B and 5000 kW is removed by gear C. 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.
