Using this experimental module, static friction and sliding friction, and the related friction vibrations and slip-stick effects can be clearly demonstrated. The unit is used in conjunction with the basic module TM 260. For the experiments, cylindrical weights are placed on a horizontally rotating stainless steel disc. This is prevented from turning by a cord. The cord is coupled to force measuring devices with a strain gauge via a tension spring. An open container surrounds the friction disc. Different lubricants can be placed in this beaker.
