Forced torsional oscillations 3D virtual laboratory work on physics (section: Mechanics).
INTENTION: Simulation of the laboratory work on general physics.
PURPOSE OF THE EXPERIMENT: Measurement and analysis of forced harmonic torsional oscillations.
DESCRIPTION: The Wheel of the Field, or the torsion (rotational) pendulum, allows the study of forced harmonic torsional oscillation. For this purpose, the oscillating system is connected to an excitation system, which is driven by a DC motor at a controlled speed, so that the return spring is periodically stretched and compressed. In this experiment, the dependence of the amplitude on the excitation frequency at different degrees of damping is measured and the phase shift between the excitation and the actual oscillation is observed.
