*Those [[designed]] for lifting, such as when used with a [http://en.wikipedia.org/wiki/Hoist_(device) 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 (The fixed third dimension being a chain's length.)

*Those designed for [[transferring]] [[power]] in [[machines]] have links designed to mesh with the teeth of the [http://en.wikipedia.org/wiki/Sprocket sprockets] of the machine, and are flexible in only one dimension. They are known as [http://en.wikipedia.org/wiki/Roller_chain Roller chains], though there are also non-roller chains such as [http://en.wikipedia.org/wiki/Block_chain block chain].
