WebForced vibrations as the name implies, happens when an object is forced by an input force (periodic in nature) to vibrate at a certain frequency. Objects that are free to vibrate have their natural frequencies in which they vibrate when left for a duration of time. Resonance occurs when objects are forced to vibrate at their natural frequency. WebIn maintained vibrations, since the energy is supplied to the oscillator at the same rate at which it is dissipated, amplitude of oscillations remains unchanged. In case of forced oscillations, amplitude of vibrations remains constant as it is understood that force is sufficient enough to provide the energy to maintain the amplitude.
