In case of forced vibration
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.

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.

The forced and resonant-vibration characteristics of a torsional system are easily enough determined by the well-known Holzer methods, in the case where the only major damping influences available in the system are those of the prime-mover itself, or of the propeller, in the case of a propeller-propulsion system. Where a damper …
