Product description
When the frequency f of the driving force acting on a linear oscillatory system changes, the phase d of the steady-state oscillations of this system and the energy W stored in it changes. Let the phase of oscillations d change by n/4 with a small frequency shift from the resonant one Df = 1 Hz. How will the energy W change in this case? What is the decay time t of the system in the free oscillation mode?
