Oscillations in a System with Two Linked Oscillators
In the last chapter we looked at the phenomenon of resonance in its simplest form, namely external resonance in a linear oscillator. If the system is not that simple, for instance it has several degrees of freedom, another effect is possible. This is the effect of internal resonance, or the resonance between individual subsystems. We shall see how internal resonance between individual (we shall call them partial) subsystems allows them to exchange energy, i.e., it is an interaction between them. Clearly, external resonance can be considered as a special case of internal resonance when the energy of one of the subsystems is infinite, in which case it ceases to be an interaction, and is rather the action of one subsystem upon the other.
