Built for engineers using it for real design work. Go from concept to a running model in the browser, then scale to the cloud when needed. Simulate a carousel live below — adjust the inputs and watch it respond, right in your browser.
Reading this result: With restitution 1 every bounce is perfectly elastic, so the total kinetic energy of all 12 balls stays constant forever — a 2D model of an ideal gas.

Tiny changes in the start explode into totally different motion — deterministic chaos. Drag either bob to set a new starting position; it pauses playback automatically.
Reading this result: Starting both arms at 90° (π/2) with lower-bob mass 10 and g 9.8 puts the pendulum firmly in its chaotic regime. Unlike a small-angle swing, which would be near-periodic, here trajectories that differ by 0.02 rad diverge exponentially — a positive Lyapunov exponent.

Yes — this version of "Rotational Dynamics for a carousel" is framed for engineers using it for real design work. Go from concept to a running model in the browser, then scale to the cloud when needed.
