Friction is the resistance of a body against movement on a base. Self-excited friction oscillations, also known as slipstick phenomenon, occur if the static friction is significantly higher than the dynamic friction. Static friction means that a body remains at rest under the action of a force. If a limit value is exceeded, the body begins to move on the base, resulting in dynamic friction.
Learning Objectives And Experiments:
Observation of the transition from static to dynamic friction
Together with the drive unit
Influence of the relative velocity of the friction partners on the slipstick phenomenon
Influence of the force between the friction partners on the slipstick phenomenon
Influence of lubrication on slipstick phenomenon.
Features;
Friction rings of different materials for the study of different friction pairings
Slip Stick phenomenon at the transition from static to dynamic friction.

The solar energy is captured by a cylindrical parabolic solar concentrator in which the parabola axis is constituted by a high thermal conductivity tube and black colour containing an adequate liquid able to capture the solar energy increasing its temperature. The Computerized Educational Equipment On The Thermal Solar Refrigeration Cycle is one of the most interesting applications of solar thermal energy because it is able to use the solar energy and, via an absorption cycle, to convert the energy in a source of cold that can be used for food conservation chain, air conditioning, chilling water and in general in all the applications of refrigeration and conditioning purposes without the use of electrical energy. The Computerized Educational Equipment On The Thermal Solar Refrigeration Cycle has been designed and manufactured by Italia to allow the experimental study of an absorption refrigeration plant using solar energy as energy source. Owing the peculiarity of the plant able to use the solar energy to convert it in a source of cold, the plant is particularly interesting in all the countries of the equatorial area, where the sun is the main energy source and the coverage of the electrical network is scarce.
