In case of a forced vibration, the resonance wave becomes very sharp when the:

Options

  1. Aquality factor is small
  2. Bdampening force is small
  3. Crestoring force is small
  4. Dapplied periodic force is small

Correct answer

B. dampening force is small

Step-by-step solution

Resonance describes the phenomenon of increased amplitude that occurs when the frequency of a periodically applied force is equal or close to a natural frequency of the system on which it acts. At resonance, the damping force becomes small enough so that the resulting oscillations have large amplitude.
