6 Questions
In the steady state, what happens to the amplitude of the forced oscillations as the difference between the forcing frequency and the natural frequency increases?
Decreases
What happens to the oscillations when free oscillations die out and only forced oscillations remain?
Oscillations reach a steady state with constant amplitude
What does A represent in equation (1.32) for forced oscillations?
Amplitude of forced oscillations
In the steady state, what is the relationship between energy input per cycle and energy lost per cycle?
Energy input per cycle equals energy lost per cycle
What do both the amplitude A and the initial phase a depend on?
Applied force's frequency wf
How is the amplitude of forced oscillations calculated according to equation (1.33)?
(Fm^2 / f^2) * (f0^2 / (ω - γω))
