What is the mechanical advantage of a machine which only changes the direction of a force?

Since the question clearly states that the machine only changes the direction there can be no mechanical advantage gained.
In order for a machine to have a mechanical advantage greater than 1, the machine must be able to change two or more of these factors:
- The amount of force exerted
- The distance over which the force is exerted
- The direction over which the force is exerted
