This is an example of a mechanical advantage in a mechanism: in its application a relatively small input force 'V' is translated into a relatively large output force 'H'. The mechanism looks like the straightening of a leg with the knee equivalent to the hinge. I have made this sketch myself. I hope it helps illustrate a very basic mechanical engineering principle.
