A solid shaft of mild steel 240 mm diameter is to be replaced by a hollow shaft of alloy steel for which allowable shear stress is 22% greater. The power to be transmitted is to be increased by 20% and the speed of rotation increased by 5%. Determine the maximum intemal diameter of the hollow shaft. The external diameter of the hollow shaft has the same value for the solid shaft.
