SUMMARY
The maximum speed of a hollow shaft with an internal diameter of 72 mm and a wall thickness of 24 mm, designed to transmit 90 kW of power without exceeding a shear stress of 150 MPa, is calculated to be 22.66 rad/s. To determine the external diameter, the formula for the outer diameter (OD) must be applied, which is essential for accurate stress calculations. The discussion highlights the importance of understanding the relationship between internal diameter, wall thickness, and external diameter in torsional stress problems.
