3. Qualitative effects of a tangential component

When a tangential force F T is superimposed on the normal force F N Hertz's theory is no longer sufficient; Mindlin's theory must be taken into account. , which describes the distribution of the shear stress field induced in the contact area by the tangential force.

In the case of dry friction contact, there is no macroscopic relative movement between the two bodies as long as the ratio
