11.A steel tire is to be heated and placed on a 72.00" diameter locomotive drive wheel hub.At 80 F the tire has an inside diameter of 71.94". The coefficient of thermal expansion forthe steel is 6.5(10-6) /F, and its yield strength for 0.2% offset is 60 ksi. Determine:(a) The temperature increase required for the inside diameter of the steel tire to be72.04" to facilitate placing it on the drive wheel hub.(b) The maximum tensile stress in the steel tire when it has cooled to -20 °F, assumingthat the diameter of the drive wheel hub does not change.(c) The factor of safety with respect to failure by slip for the stress obtained in part (b).

Answered: 11. A steel tire is to be heated and…
