Ch. 3: Forced Vibration of 1-DOF System Resonance is defined to be the vibration response at ω=ω n, regardless whether the damping ratio is zero. At this point, the phase shift of the response is -π/2. The resonant frequency will give the peak amplitude for the response only when ζ=0. For ,the peak
