Vibration - Wikipedia

Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point.The word comes from Latin vibrationem ("shaking, brandishing"). The oscillations may be periodic, such as the motion of a pendulum—or random, such as the movement of a tire on a gravel road.. Vibration can be desirable: for example, the motion of a tuning fork, the reed in a woodwind instrument or ...
