Humans use simple machines every day, possibly without even noticing. A car, for example, uses its axles and wheels to make moving easier by redistributing the force caused by its bulk onto more mobile surfaces, and parts of a car are held together by screws or tightened or loosened by a wrench, an applied use of leverage.
There are two types of mechanical machines: simple and compound. A simple machine is composed of only one mechanical apparatus, while a compound machine comprises two or more simple machines. Simple machines provide a mechanical advantage, which is the factor by which a machine increases the magnitude of a force.
As a machine, a pair of scissors seems pretty simple, though it's actually a complex machine. A scissors combines two levers with the cutting action of the wedge. The levers multiply the force on the object to be cut, making it easier to use and more effective than a knife.
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:. Lever

VEX IQ Curriculum - Simple Machines & Motion ... it may be hard to see similarities, but a screw is actually just another kind of inclined plane. One example of how a screw helps you do work is that it can be easily turned to move itself through a solid space like a block of ...
What Is a List of Simple Machines? There are six simple machines, including the lever, the wheel and axle, the inclined plane, the wedge, the screw and the pulley. Together, these six form the basis of all mechanized systems that have ever been built.
These simple machines create a greater output force than the input force; the ratio of these forces is the mechanical advantage of the machine. All six of the simple machines have been used for thousands of years, and the physics behind several of them were quantified by Archimedes. These machines can be used together to create an even greater ...
Example: Activity: 1. Pulley - How Stuff Works. A pulley is a simple machine that uses grooved wheels and a rope to raise, lower or move a load. Pulleys . 2. Lever - Enchanted Learning animations. A lever is a stiff bar that rests on a support called a fulcrum which lifts or moves loads. Levers. 3. ...
