🏗️ Tuned Mass Damper: Ground-Excited Resonance and Frequency Response (2D side view)

Side view of a heavy carriage on springs shaken by the ground, with a small tuned absorber mass on top: tune the absorber and the resonance peak collapses. Same two-degree-of-freedom base-excited model as the 3D page, with live frequency-response curves and four numerical checks.
