    Simple Machine: Wood Block & Tackle Model

    One pulley can be used to change the direction of the force applied by a cord several pulleys can be used to make this simple machine. A small force on the cord can be used to lift a large weight. Experimenting with the device shows why: lifting the block by a short distance requires that the cord be pulled a long distance.
