Some machines do not have any effect on the effort force that you exert. They simply change the direction of the effort force. For example, when you pull down on the cord of window blinds, the blinds go up. Only the direction of the force changes. The effort force and the load are equal, so the mechanical advantage is 1. What are some other mechanical devices that have a mechanical advantage of 1?
