Chain

July 10th, 2008

A chain is a series of connected links. This article is about the literal, physical chain. A chain may consist of two or more links.

A chain is usually made of metal.

Chains are usually made in one of two styles, according to their intended use:

* Those designed for lifting, such as when used with a hoist; for pulling; or for securing, such as with a bicycle lock, have links that are torus shaped, which makes the chain flexible in two dimensions.

* Those designed for transferring power in machines have links designed to mesh with the teeth of the sprockets of the machine, and are flexible in only one dimension. They are known as Roller chains.

Chains can also be decorative as jewellery.
