The Types of Simple Machines Found in Your Home Inclined Planes: Up and Down. An inclined plane is a flat surface where. The Cutting Wedge. The wedge is an inclined plane that moves. Turn of the Screw. A screw is an inclined plane wrapped around an axis. Lever and Fulcrum: Force Multiplier. A simple machine is a mechanical device that changes the direction or magnitude of a force. In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called leverage) to multiply force. Usually the term refers to the six classical simple machines that were defined by Renaissance scientists.
How are skyscrapers built? What makes it easy to chop up vegetables? What makes a propeller on an airplane turn? Simple machines make the things in everyday life work. Scientists define a simple machine as a device that alters either the direction or force of an object. In other words, they magnify, or enlarge, the amount of force that someone can apply to an object so that it takes less work to move it. These simple machines are often used in more complex devices, like airplanes and cranes. There are six primary types of simple machines: pulley, screw, inclined plane, wheel and axle, wedge, and lever. These simple machines are used in more complex devices every day, making tasks much easier.
Simple machines make tasks simpler by reducing the amount of effort it takes for humans to perform certain tasks.
Levers, pulleys, and inclines all have one thing in common: they reduce the amount of energy it takes for human to move or lift objects. This site explains the terms used when talking about simple machines and what students need to know about them.
For older students, this introduction to machines explains how they work as well as the difference between machines, simple machines, and mechanisms.
