The inner and outer radii of a hollow steel shaft are 50 mm and 100 mm, respectively. The hub of a steel gear wheel that is shrunk onto the hollow shaft has an outer radius of 150 mm. The maximum allowable tangential stress developed by shrinking the gear wheel onto the hollow shaft is 200 MPa. The length of hub parallel to the shaft axis is 200 mm, and the coefficient of static friction between the hub and the shaft is 0.40. Determine the maximum torque that may be transmitted by the gear wheel without slipping on the shaft.

Question
The inner and outer radii of a hollow steel shaft are 50 mm and 100 mm, respectively. The hub
of a steel gear wheel that is shrunk onto the hollow shaft has an outer radius of 150 mm. The
maximum allowable tangential stress developed by shrinking the gear wheel onto the hollow
shaft is 200 MPa. The length of hub parallel to the shaft axis is 200 mm, and the coefficient of
static friction between the hub and the shaft is 0.40. Determine the maximum torque that may be
transmitted by the gear wheel without slipping on the shaft.
