A chain is a series of connected links made of metal. A chain is made of two or more links.
– Those designed for lifting (such as when use 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 like designed to mesh with teeth of the sprockets of the machine. They are flexible in one dimension only.
