The case
Same spool, same 100 N harmonic excitation, same damping. The only thing that changes is where the support sits. At 29.3 Hz, relocating the support cuts the drive-point amplitude by 96 %. At 37.8 Hz, that same decision multiplies it by 5.8. A support does not remove the problem; it moves it to another band.
