For the mathematical background, please read the Wikipedia page on catenary curves.
| Number of zigzags: 2 ≤ 20 ≤ 50 |
| Length of the chain (w.r.t. the canvas width): 120% ≤ 180% ≤ 300% |
The animation stops when the potential energy grows or decreases by ≤.
The full potential energy of the chain is E=--.
The maximum norm of the gradient vector is |∇|=--.
