A gear of inner and outer radii 0.1 and 0.15 m, respectively. is shrunk onto a hollow shaft of inner radius 0.05 m. The maximum tangential stress induced in the gear wheel is 0.21 MPa. The length of the gear wheel parallel to shaft axis is 0.1 m. Assuming a coefficient of static friction of I = 0.2 at the common surface, what maximum torque may be transmitted by the gear without slip?
