WebMar 8, 2024 · These vibrations occur in the absence of external forces like friction after the release of the body. Simple pendulum is an example for this. Note: As we know, all vibrations are not forced vibrations. The swing and simple pendulum are working with free vibrations. In these cases, we won’t apply any external forces after the release of the body. WebForced vibration is when an alternating force or motion is applied to a mechanical system. Examples of this type of vibration include a shaking washing machine due to an imbalance, transportation vibration (caused by truck engine, springs, road, etc), or the vibration of a building during an earthquake.
