catenary
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.
