Abstract
The article describes the results of an experimental study of the natural frequencies of oscillations of a mechanical system influence on the angular velocity of a pendulum mounted with the possibility of free rotation on a rotating shaft of an electric motor. It is established that at a constant moment of friction in the pendulum support, providing for a change in its mass moment of inertia, a mode of motion takes place in which the motor shaft rotates at a working angular velocity, and the angular velocity of the pendulum coincides with one of the natural frequencies of the oscillations of the mechanical system. The studies have also shown that there are ranges of the values of moments of inertia of the pendulum mass. For these moments of inertia, one can observe the establishment of a stable or unstable angular velocity of the pendulum, which is equal to one of the natural frequencies of the oscillations of the mechanical system.
