At a temperature of 90°C, a steel tire 10-mm thick and 75mm wide that is to be shrunk onto a locomotive driving wheel 1.8-m in diameter just fits over the wheel. Determine the contact pressure between the tire and the wheel after the assembly cools to 20°C. Neglect the deformation of the wheel caused by the pressure of the tire. Assume a=11.7 µ m/ (m ºC) and E=200 x 10° N/m?.
