Question

under what

special case

resonance occur?

Answer 1

Hey friend
here is your answer

Resonance is a special case of a forced vibration. when the frequency of externally applied periodic force is equal to the natural frequency of the body, the body readily begins to vibrate with an increase in amplitude. This phenomenon is called Resonance.
Resonance occurs only when the applied force caises forced vibration in the body and the frequency of the applied force is exactly equal to the natural frequency of the body.


glad to help you
hope it helps
thank you.

Answer 2

Hey.

Here is the answer.

The condition for resonance are following :

1. The object must have at least one natural frequency.

2. The frequency of the external vibration must match the object's natural frequency.

3. There must be an external driving force with certain frequency.

Thanks.
