FREE AND FORCED VIBRATIONS

Bench top apparatus that investigates the free and forced vibrations of a rigid beam with a spring, and a simply supported beam. Demonstrates Rayleigh's approximation and Dunkerley's method.

A bench-top unit to demonstrate free and forced vibrations of two mass-beam systems:

The frame has a low natural frequency, so the vibrations of the systems do not affect it. The frame has two sections: an experiment 'window' to the right and a control panel to the left. The experiment window contains the beam, spring and other parts used in the experiments. Learn about FREE AND FORCED VIBRATIONS exporters for optimal educational outcomes..
