A steel tire, 10 mm thick, 80 mm wide, and 1500 mm inside diameter, is heated and shrunk onto a steel wheel 1500.5 mm diameter. If the coefficient of static friction is 0.30, what torque (kN.m) is required to twist the tire relative to the wheel? Neglect the deformation of the wheel. Use E = 200 GPa. 10 mm 1500 mm 10 mm
