A wheel of diameter 150.0 mm and width 37.00 mm carrying a load 2.200 kN rolls on a
flat rail. Take the wheel material as steel and the rail material as cast iron. Assume the
figure given, which is based on a Poisson's ratio of 0.3, is applicable to estimate
the depth at which the maximum shear stress occurs for these materials. At this critical
depth, calculate the Hertzian stresses σr, σy, σz, and Tmax for the wheel.
