Case: A solid shaft is to transmit 250 kW at 180 rpm. The torsional shear stress is not to exceed 110 MPa. Without changing the length, material, and allowable stress, it is replaced by a hollowed section whose internal diameter equals 0.6 of the external diameter.
Question 1. Determine the diameter of the solid shaft.
Question 2. Determine the external diameter of the hollowed shaft.
