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

The set contains 18 aluminium drawing models. The cylindrical models have cut-outs parallel to, and at an angle to, the main axis. The models are precision-manufactured and are suitable for measurement exercises as well as drawing exercises. The geometric models support the learning process by providing an introduction to technical drawings: from the solid model to the more abstract representation of the three views in a technical drawing. Two students can easily work with one model set. For optimal learning, it is recommended that students work independently from each other on these exercises.

The Compression Ratio can be changed without stopping the engine and without altering the combustion chamber geometry by means of a specially designed tilting cylinder block arrangement. Setup is provided with necessary instruments for combustion pressure and crank-angle measurements. Computerized Variable Compression Ratio Engine Test Bed allows to perform experiments concerning this kind of engines. The unit consists of single cylinder, four stroke, Variable Compression Ratio (VCR) engine connected to eddy current type dynamometer for loading. Provision is also made to interface airflow, fuel flow, temperatures and load measurement. Rota meters are provided for cooling water and calorimeter water flow measurement. The test bed includes a stand-alone panel box consisting of air box, two fuel tanks for duel fuel test, manometer, fuel measuring unit, transmitters for air and fuel flow measurements, process indicator and engine indicator.

Commercial components are used in practical experiments. These components are mounted on plates ready to be connected and are arranged clearly in the frame. This allows for the defrosting of an iced-up evaporator by operating it temporarily as condenser. Manometers provide an insight to the pressure ratios in the refrigeration circuit. The set includes complex refrigeration components, such as capacity controller, start-up controller, defrost timer, 4/2-way reversing valve and refrigeration controller. The 4/2-way reversing valve, for example, is used to reverse the circuit.
