Damped and forced oscillations, resonance — practice question
For an oscillating body, state what is meant by
(a(i))[1]
forced frequency.
(a(ii))[1]
natural frequency of vibration.
(a(iii))[2]
resonance.
(b)[2]
State and explain one situation where resonance is useful.
(c)[2]
In some situations, resonance should be avoided. State one such situation and suggest how the effects of resonance are reduced.
