The bench is a foundation on height-adjustable legs. A vertical rod with an optical sensor is fastened on the foundation. A rotating frame is suspended on a steel thread on the upper bracket. A clamping plate of the rotating frame can freely move along the rails, changing the area necessary for fixing the test pattern. The thread tension can be adjusted by the tension screw.
An electronic stopwatch is used for timing the pendulum oscillation.
Software and a set of methodological and technical documentation intended for academic staff are supplemented to the laboratory bench.
