Simulation of a mechanical rotational system with a friction element

This example will demonstrate the simulation of a mechanical rotational system with a friction element. Inertia is connected to the support by means of a spring and a damper. It is driven by a speed source through a friction element. It, in turn, has a difference between tear-off and Coulomb friction, which leads to intermittent movement.
