The Lever goes by the distance vs force rule. If the distance of the effort arm is longer then the distance of the load arm, it takes less force. If the distance of the load arm is longer then the distance of the load arm, it takes more force. This law or rule applies to all three classes of levers. Here is a video on how the lever works:
