A simple machine is a manual device that reduces the effort needed to perform a certain amount of work. These mechanisms alter the direction or magnitude of a force to help increase the ability to lift, push and pull objects.Continue Reading
Simple machines enhance the total output force while proportionally decreasing the distance traveled by the load.
Simple machines are the building blocks that compose all complex machines. The six types of simple machines are the wedge, ramp or inclined plane, screw, lever, wheel and axle, and pulley. These are the simplest mechanisms that apply leverage to magnify force. One or a combination of these devices enable a person to use less force or to apply force in a direction that's easier to maneuver.Learn more about Motion & Mechanics
A staircase is an example of the inclined plane simple machine. A spiral staircase, however, is categorized as a screw. Another common example of an incline plane is a ramp.Full Answer >
A hammer is a lever, one of the six types of simple machines. A lever is defined as any rigid bar that pivots around a fixed point, called a fulcrum, to apply force.Full Answer >
The zipper is a wedge, which is a simple machine that works by putting two inclined planes side by side so that they create a sharp edge. A zipper has two lower wedges that permit it to close and a single upper wedge that allows it to open.Full Answer >
A hammer is classified as a simple machine called a lever. Levers feature a fulcrum, applied force and load. The three types of levers—class one, class two and class three—are distinguished by the placement and relationship of these elements.Full Answer >
