This apparatus enables experiments to be performed on rotational motion in general. The arrangement is fitted to a low friction ball bearing mounted rotating drum. The system is accelerated by a metal weight attached to a cord wrapped around the drum. Weights can be fitted to a rotating rod at marked distances from the centre. A dumb bell-shaped arrangement is thus created; the inertia properties of this arrangement can be changed easily and recalculated. The experiment is set up quickly using table clamps and stands; it is ideally suited to group work for 2-3 persons. The time taken for the weight to fall is measured using a stopwatch, the moment of inertia of the object can then be determined.

The Basic Module Water Pumps is part of an equipment series that facilitates the investigation of a wide range of engines and machines. The pumps are installed in the experimental set-up using flexible hoses with rapid action couplings. The flow rate is set on a ball-cock and acquired with a magneto-inductive flowmeter. The sensors for intake and delivery pressure are fitted to the pumps to be investigated. Different water pumps can be operated on the basic module and investigated in respect of their characteristic behaviour. The drive motor for the pump drive is fitted to the Universal Drive and Brake Unit. All sensors are connected to the measuring unit that is part of the basic module. The measured values recorded are displayed on digital displays on this block.

Mono-Jetronic always had adaptiveclosed-loop lambda control, and due to the simple engine load sensing, it isheavily dependent on the lambda sensor for correct functioning. Digital fuel injection. There are no sensorsfor air flow, or intake manifold vacuum. This system features one centrally positioned fuel injection nozzle Mono-Jetronicis different from all other known single-point systems, in that it only relieson a throttle position sensor for judging the engine load.

The bending can be mounted vertically (standing or hanging) or horizontally into the frame by varying the free clamping length or moving additional weights, the natural frequency of the bar is changed. The additionally required sensor supply module processes the signal for its display on an oscilloscope (not supplied). The bar is deflected manually to start damped vibrations. A non-contact position sensor measures the corresponding amplitudes.
