A hook isn't really a "machine" at all. Depending on its construction, in a particular application it might be operating as a lever, or possibly as an inclined plane, but it's really not possible to say with any certainty what kind of simple machine it is without more details of exactly what the hook is doing. It may not be any kind of simple machine.
