Have you noticed vibrations in a drill machine or in a washing machine ? How do they differ from vibrations in the above two cases ? |
|
Answer» Vibrations in the body of a drill machine or that of a washing machine are forced vibrations induced by the vibrations of the motors of these machines. On the other hand, the oscillations of a simple pendulum or a guitar string are free oscillations, produced when they are disturbed from their equilibrium position and released. |
