Serpentine Belt Chirp/Squeal: in-depth Diagnosis

Two years and 30k miles ago I put a brand new serpentine belt on my car. Recently the belt has developed a very annoying chirp/squeal that is present all the time. WHY?

Here I take a look at all the factors that make a serpentine belt run nice and smooth and quiet. We discuss
-pulley misalignment
-belt tension
-belt wear
-OTHER VARIABLES!

We discover that the problem in this case is not very common, but needs to be addressed nonetheless. Also, you may have more than one problem, so a complete diagnosis in not a waste of time!
