Homework Statement
At the natural frequency,ω0 what are the real and imaginary components of Avel(ω) ?
Sketch a phasor diagram with the velocity vector and driving force vector,and use this to provide the phase difference between Avel(ω) and the driving force if ω=ω0 (ι.e at resonance),
and in case ω<<ω0,state whether the velocity leads or lags the driving force
Homework Equations
Avel(ω)=(F0 iω )/[m (ω^2 -ω0^2 +iγω)] where γ=b/m
The Attempt at a Solution
in the first case where ω=ω0 ,maybe the imaginary part of Αvel(ω) is zero since ,Avel(ω)=F0/mω^2 =F0/k
