Problem
Consider a tyre of a cylindrical shape and of a radius R s an inner radius rwidthd filled up to a pressure of p. We push down on the tyre with a force F. With this encumbrance the shape of the tyre changes from a cylinder to a cylindrical segment with the same inner and outer radius. Assume that the temperature of the tyre will not change. Determine the contact area of the tyre and road.
