The excitation frequency (left pendulum) is smaller than the natural frequency of the right pendulum. If these two frequencies are not approximately equal, no resonance can occur in this forced oscillation.

I honestly wouldn’t call that forced vibration. Hir there are self-modes with which the system swings. In response, I understand something else.
