Vibration Lab
Resonance, made visible. Drag the damping ratio ζ and the forcing frequency ratio r = ω/ωn; the steady-state magnification curve redraws against a faint family of reference damping curves, with the resonant peak marked. Light damping near r = 1 makes the response blow up; adding damping tames the peak (and past ζ = 0.707 it vanishes). Flip to transmissibility to see why vibration isolation needs r > √2 — and why more damping there actually hurts.

Peak at r
Drive a system near its natural frequency (r→1) and a lightly-damped response blows up — that's resonance. Adding damping (ζ) tames the peak; past ζ = 0.707 the peak disappears entirely.
