# What is an easy definition of mechanical advantage?

Definition of mechanical advantage. : the advantage gained by the use of a mechanism in transmitting force; specifically : the ratio of the force that performs the useful work of a machine to the force that is applied to the machine.

Furthermore, what does mechanical advantage of 4 mean?

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device preserves the input power and simply trades off forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever.

What is an example of a mechanical advantage?

force person lever example. The term mechanical advantage is used to described how effectively a simple machine works. Mechanical advantage is defined as the resistance force moved divided by the effort force used. Sometimes the mechanical advantage of a machine is less than one.

How do you calculate the mechanical advantage?

Calculate the mechanical advantage of a lever. In the previous chapter, you learnt that you can calculate a quantity to say exactly how big or smallthe mechanical advantage is. This quantity is a ratio.It is calculated by dividing the output force by the input force. A ratio of 1 to 4 is written as 1:4.
