Solution to Problem 208 Axial Deformation

Problem 208
A steel tire, 10 mm thick, 80 mm wide, and 1500.0 mm inside diameter, is heated and shrunk onto a steel wheel 1500.5 mm in diameter. If the coefficient of static friction is 0.30, what torque is required to twist the tire relative to the wheel? Neglect the deformation of the wheel. Use E = 200 GPa.

Solution 208


Mr. Verterra,

I think this problem needs more illustration, detailed illustration. I cannot seem to distinguish between a tire and a wheel. Also, why does the value of the length has a pie symbol next to it. Kindly explain. Thank you Sir.
