Dan, I didn't think it was possible for you to confuse me more, but it seems that you have.
So was I right in my supposition of the arc? Can you effectively raise one end of the treadmill the 60 inches and have it hit a 90 degree angle at it's pinnacle? I don't think so, as the one end of the treadmill would act as the center of a circle, and the other end of the treadmill would effectively be travelling around the circumference of the circle, which would make it longer. That is why you can't calculate the circumference of a circle simply by calculating the length of the radius, you must bring Pi into the equation, otherwise you're calculation will be off.
