Well as the subject states, I need some info. I've got a few SAE technical articles, but I would like to find a couple good websites that kind of "dumb down" the topic so I can make it sound easier to comprehend to someone without an engineering background.
I'm an undergrad mechanical engineer, and I have to write a paper and do a presentation over this topic, and I have to format it in a way in which to explain the concept to the average "Joe Schmoe"
I seem to remember a post about this a year or two ago, but couldn't find it in the archives. PKRWUD I believe you were a part of the thread (but its hard to find one that you aren't

) Got any info for me? Or a good place to look?
thanks,
