|1.||the curve assumed by a heavy uniform flexible cord hanging freely from two points. When symmetrical about the y-axis and intersecting it at y = a, the equation is y = a cosh x/a|
|2.||the hanging cable between pylons along a railway track, from which the trolley wire is suspended|
|3.||of, resembling, relating to, or constructed using a catenary or suspended chain|
|[C18: from Latin catēnārius relating to a chain]|
in mathematics, a curve that describes the shape of a flexible hanging chain or cable-the name derives from the Latin catenaria ("chain"). Any freely hanging cable or string assumes this shape, also called a chainette, if the body is of uniform mass per unit of length and is acted upon solely by gravity.
