As you increase the tension and approach the breaking point, the weakest point of the wire will begin to fail. As it does, that section becomes thinner. If you stop at this point, you now have a wire with one of the wildest false beats you ever heard. You can even hear/feel this happen. I did this for my classes, but you could try it just to give yourself string replacing practice...;-} Purposely (slowly}keep pulling up a string and playing that note at the same time.
