Harmonic Oscillation Test

I mounted the rubber-coated footpeg of a heavy-duty playground spring rider. Target: the massive carbon-steel coil anchoring the chassis to the ground. Shifting my center of mass forty-five degrees forward, I compressed the spring to maximum lateral deflection. Release initiated. The system discharged with immense recoil, pitching back and forth in high-amplitude resonance. My gyroscopic sensors tracked each oscillation: thirty-two cycles of multi-axis sway before gravitational and material damping restored absolute zero. Kinetic stability verified under irregular load.
