An electric motor pulls the cable, lifting the car between floors. Compound machines, like the cutting of an object, are made up of two or more simple machines that work together to exert more force efficiently. The stapling plate is known as the anvil. When a force is used to move something, work is done. The principle of the inclined plane is used widelyfor example, in ramps and switchback roads, where a small force acting for a distance along a slope can do a large amount of work. By attaching a hook to the cord, the wheels rotation can be used to raise or lower objects, making work easier.
