A steel tire has a dimensions indicated in the figure below. At 78 degrees Celsius, the said tire was fit into a 1.8m to an engine wheel with 24 degrees Celsius. Calculate the contact pressure between the tire and the wheel after fitting together due to colling of 24 degrees Celsius. The coefficient of expansion due to temperature of the tire is 12.3 micrometer/ m- degrees Celsius and Modulus of Elasticity is FN GPa.
