The training laboratory system  is designed to conduct laboratory experiments in “Physics” and provide the study of physical pendulum damped oscillations.

The bench is a foundation on height-adjustable legs. A vertical rod is fastened on the foundation. At the upper end of the rod a vibration sensor, which is intended for detecting the rod angular deviation, is mounted. The rod is secured in the bearing, which is the axis of rotation. A load, a dry friction element (brush), and a viscous friction element (thin disk) are fixed along the rod. The rod itself can change the point of rotation, changing thereby the moment of inertia.

When the brush is interacting with the friction surface, the dry sliding friction force emerges. The air resistance gives rise to viscous friction forces. Moments of forces can be changed by altering the arm of force with respect to the axis of rotation.

To connect the unit to a PC, the electronic module is used. Power is supplied from the PC.

Software and a set of methodological and technical documentation intended for academic staff are supplemented to the laboratory bench.
