Find the internal diameter of the tire if after shrinking on, the hoop stress in the tire is 100 MPa. Assume E=200kN/mm2. Also find the least temperature to which the tire must be heated above that of the wheel before it could be slipped on. The coefficient of linear expansion for the tire is 6.5×10–6 per °C.arrow_forward
