A wheel of diameter d and width w carrying a load F rolls on a flat rail. Assume that Figure 3–40, 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
, and τmax for the wheel.
