The displayed change of the frequency response (resonance point), has its cause
in a so-called two mass system (caused by the elastic coupling of two masses).
As, upon closer examination, each mechanic coupling shows a certain elasticity, it
is no the question if there is a resonance point, but at which frequency it is and how
well it is attenuated.
