⛓️ Catenary (2D)

Interactive 2D catenary simulation. Drag the two endpoints of a hanging chain and watch the exact curve y = a·cosh(x/a) update in real time. Adjust chain length, compare with a parabola, and see the live formula overlay.

⚙ Under the hood

Drag the two endpoints of a hanging chain in this 2D canvas simulation and watch the exact catenary curve y = a·cosh(x/a) update in real time. Adjust chain length and sag, overlay the live formula, and compare the true curve against a parabola.
