SUMMARY
The discussion focuses on calculating the external diameter of a hollow shaft required to transmit 60 kW of power at 4000 revolutions per minute (RPM), with an internal diameter that is three-quarters of the external diameter and a maximum permissible shear stress of 48 MPa. Key equations include the relationship between torque and power, where power (P) equals torque (T) multiplied by angular velocity (ω). The necessary calculations involve determining torque from the given power and RPM, followed by applying shear stress formulas to find the external diameter.
