In case of a forced vibration, the resonance peak becomes very sharp when the (a) damping force is small (b) restoring force is small (c) applied periodic force is small (d) quality factor is small

Answer: (a). Sharpness of resonance is measured by the quality factor Q = (mω₀)/(b). Small damping gives large Q and a sharp, tall peak, answer (a).

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

Show answer and solution

Answer: (a)

Sharpness of resonance is measured by the quality factor $Q = \frac{m\omega_0}{b}$ .
Small damping gives large $Q$ and a sharp, tall peak, answer (a).
