Abstract
The easiest structures to think about are generally those which have to resist only tensile forces — forces which pull rather than push — and, of these, the simplest of all are those which have to resist only a single pull: in other words unidirectional tension, the basic case of a rope or a rod. Although simple unidirectional tension is sometimes to be seen in plants — especially in their roots — the muscles and tendons of animals provide better biological examples and so do vocal cords and spiders’ webs.
