73. Explain how the window washer lifts his platform using the pulley system. Refer to the diagram to describe what happens when the force is exerted. Does the pulley system increase or decrease the input force needed? As a result of using the pulley, what happens to the direction of the force? Click on screen to continue

74. The pulley system increases the distance over which the force is exerted, decreases the input force needed, and changes the direction of the force. To pull himself toward the top of the building, the window washer pulls down on a rope. The distance the window washer must pull the rope (the input distance) is much greater than the distance he moves (the output distance). When the input distance of a machine is larger than the output distance, the output force is larger than the input force.
