hanicalSimple Machines and its Mechanical Advantage
What are Simple Machines? What do we mean by Mechanical Advantage?
Simple Machines * creates a greater output force than the input force
Therefore since work is performed by applying a force over a distance, with the use of these machines we can do more work with lesser effort than working with our bare hands. In short, they make work easier.
Mechanical Advantage * The Ratio between the input force and the output force. * The measure of the force amplification achieved by using a tool, mechanical device or machine system.
Anyway what is input and output force? Input refers to the force you applied while output refers to the resultant force the object has from the input force.
Example: I pushed a ball with 10 N of force, it is rolling with 10 N of force. I input 10 N into it, now it is outputting 10 N.
The Six Classical Simple Machines
The Lever(French word that means “to raise”) * A simple machine that allows you to gain a mechanical advantage in moving an object or in applying a force to an object. It is considered a "pure" simple machine because friction is not a factor to overcome, as in other simple machines.
