Question

At resonance, the amplitude of vibration is ______

Answer 1

at resonance the amplitude of vibration is -6012439 I. m not sure
displacement of a vibration from its position of rest (arithmetic mean) up to its maximum value. 

Answer 2

Answer:

 At resonance, the amplitude of vibration is MAXIMUM.

Explanation:

• Resonance is the phenomenon of accelerated amplitude that takes place while the frequency of a periodically carried out force (or a Fourier factor of it) is identical to or near a natural frequency of the device on which it acts.

• The Resonance frequency is the vibration of a system at its natural or unforced resonance.

 Whenever , resonance is equal to resonance frequency(also known as fresonance) then the amplitude of vibration becomes maximum.
