You'll need to put together some more info to obtain an answer, besides a pretty picture.

Who's the wench, Miley Cyrus?

Okay, Say the wench has a spring scale attached to it. The spring scale says its pulling at 50 newtons right now. How do i get the force applied when i release the arm from the wench?

Well, for a start, identify what the lines in the picture mean, along with a description of what you are trying to do. Once that is done, then you need to specify what materials you want to use for the various parts and their sizes, etc. You know what it is you want to do. You have to describe it to others in order for them to understand.

Is it at all possible that you meant "wrench" rather than "wench"?

No, it's an all-too-common mistake to confuse 'wench' [a female servant] with 'winch' [a mechanical device for hoisting].
