Here is a physics site for non-physics people that has a very good explanation of mechanical advantage;
For more information on mechanical advantage check out this site, it has a through discussion on what is mechanical advantage, what systems produce it, and how to calculate it. Warning: We will not be covering any rotation in PH201. Also, there is a small discussion on work. As we have not covered this yet feel free to ignore it.

Below are a few extra websites. Please feel free to check them out if you still have questions on mechanical advantage.

A simple site that looks at mechanical advantage. This site is a good supplemental too, but it does not cover the topic very well, and there is little mention of mechanical advantage itself.

Here is an old cartoon discussing Mechanical Advantage(we will not be doing any levers this term);
