Simple Machines Most people think of machines as complex items such as bank machines, refrigerators, cars, or airplanes. However, any device that transmits or modifies force or torque for a specific purpose can be called a machine. For example, a screw and a simple wheel are machines. Simple machines are devices with few or no moving parts at all that are used to perform work by means of changing force and motion. They are the simplest devices that use mechanical advantage (defined below) to increase force. These devices are called simple machines.
