Times Square Ball Drop: Descent Mechanics

Interactive 2D simulation of the real motor-controlled cable descent behind the Times Square New Year ball — a proportional-integral feedback loop, not free fall, keeps the 60-foot drop tracking exactly one foot per second.

Engineering & Materials2DEasy60 FPS📱 Mobile-adapted⇄ 3D version

This simulation models the real motor-and-cable control system behind the Times Square New Year ball, side-on: a fixed 60‑foot pole, a cable running over a pulley to a winch motor, and a feedback controller that keeps the descent tracking a strict one‑foot‑per‑second schedule despite wind gusts and friction variation — never a free-fall drop. Click the pole or the button below to arm the countdown, then watch the target (ideal) height and the actual (controlled) height track each other, and the tracking error, motor speed and cable tension update live. Adjust the controller gain, wind disturbance, friction variation and motor lag to see how each pulls the real descent off — or keeps it on — the ideal schedule.

⚙ Under the hood

A side-view motor-and-cable winch lowers the ball down a fixed pole under proportional feedback control, holding a strict 60-second, one-foot-per-second descent against wind and friction disturbances rather than free fall.
