What is the difference between free and forced vibration?
Free vibration Forced vibration 1. In the case of free vibration, no transfer of energy is happening between the surrounding and the vibrating object.
2. A type of vibration in which a force is applied once and the structure or part is allowed to vibrate at its natural frequency is known as free vibration.
3. When a mechanical system is set off with an initial input and then allowed to vibrate freely, free vibration occurs.
4. A plucked guitar string is an example of free vibration.
1. Meanwhile, in forced vibration, there is always a force that causes energy transfer between the surrounding and the vibrating object.
2. The forced vibrations are the vibrations of a body that are constantly influenced by an external periodic force acting on it.
3. The frequency of vibrations is determined by the source of vibrations and the frequency of the driving force.
4. When a guitar is played, the vibration are produced by the strings of the guitar are the forced vibrations.
