Something I have always wondered.

My point is that the underlying force behind "friction" and the "normal force" (which are not real independent forces) is the same thing, and it is present here, regardless of the value of the "Coefficient of friction."

I'm not sure what you mean by this, so I'll let you elaborate first.

Thank you all for your answers.

I can see that I will learn a lot here!

There is no practical application. I get a lot of free time at work because working on cars has turned into a boring and tedious job so I have plenty of time to think about random crap that will make no difference in my life.
