In physics and geometry, a catenary is the curve that an idealized hanging chain or cable assumes under its own weight when supported only at its ends in a uniform gravitational field.
This chain, whose ends hang from two points, forms a catenary.
Three chains enclose a figure bounded by catenary arcs (analogous to the arbelos or parbelos).
The silk on this spider web forms multiple elastic catenaries.

In architecture, the funicular curve is an approach used to design the compression-only architectural forms using an equivalence between the rope with hanging weights and standing arch with its load.
Catenary
…bounded by two parallel circular rings. The catenary is also called the alysoid, chainette, or, particularly in the materials sciences, an example of a funicular. Rope statics describes catenaries in a classic statics problem involving a hanging rope. Mathematically, the catenary curve is the graph of the…
