WebbStresses formed by the contact of two radii can cause extremely high surface stresses. The application of Hertzian Contact stress equations can estimate maximum stresses produced. These stresses can then be analyzed in context of the application. In many cases, the resultant stresses are not of design significance, but in some cases failure … WebbWe actually see this very explicitly in the last equation. In both cases, the stress (normal for bending, and shear for torsion) is equal to a couple/moment (M for bending, and T for …
