The answer depends on exactly how the pulley is rigged - how many times the rope goes back and forth between the pulleys (if any) is crucial to figuring it out.....

Not to be overly pissy, but could you kinda describe it a bit better? You know...... With dimensions 'n stuff?
Maybe put a picture up on photobucket or some such?
