Definition & Meaning
Simple machines are fundamental mechanical devices that alter the direction or magnitude of a force. They consist of a small number of moving parts and are designed to make work easier. The six classical types of simple machines include the lever, wheel and axle, pulley, inclined plane, wedge, and screw. Each type serves a unique purpose and can be found in various applications, from household tools to complex machinery.
For example, a lever allows a person to lift a heavy object with less effort by applying force at one end while the object is positioned at the other end. This principle of mechanical advantage is central to how simple machines function.
