Description Générale

This module allows to demonstrate the static friction, the sliding friction, the related friction vibrations and the slip-stick effects.

Several weights are placed on a horizontally rotating friction disc. It is prevented from turning by a cord. This cord is coupled to force measuring devices with a force sensor via a tension spring. An open vessel surrounds the friction disc to place different lubricants.
