mechanical advantage
Beakman defines machines and acts like Archimedes to explain why a screw is a machine. He illustrates how he used a screw mechanism to remove water from a container to reduce the amount of work required to complete the task. Beakman then explains more about mechanical advantage and simple machines like the inclined plane.
