Physics · Mechanical Vibrations
In a vibration isolation system under undamped forced vibration, the amplitude of steady-state response for forcing frequency ω on a system with natural frequency ωn (and no damping) becomes infinite, when:
- 1ω < ωn
- 2ω = ωn✓
- 3ω > ωn
- 4ω = 0
Correct answer
ω = ωn
