The amount of effort saved when using machines is called mechanical advantage (MA). Simple machines use mechanical advantage as a key property to their functionality, helping humans perform tasks that would require more force than a person could produce. We will use the lever as an example of a simple machine to illustrate the concept of mechanical advantage.
In this course you will learn how to:
Fraction comparison with lowest common denominators.
Use the dynamic worksheet to practice simplifying expressions with fractional exponents, rewriting them as radicals.
This video explains how to order fractions by their size.
Three activities which illustrate the law of exponents.
This is a simple video which describes how indices problems are solved using simplified laws.
In this unit we will learn how these factors can affect the output of a simple machine. We will also learn about the difference between ideal mechanical advantage (IMA) and actual mechanical advantage (AMA), and how to apply your knowledge to calculate the efficiency of various simple machines.
YouTube video that explains how to use prime factorization to find the highest common factor and lowest common multiple. It is very simple using the method described in the video.
