Remember...a spring is really nothing more than a straight torsion bar that has been wound. Or another way...a straight lever that has been been wound. If you shorten that torsion bar/lever, you are changing the leverage. You are increasing its resistance to bending. So by cutting a spring..you are shortening that lever...therefore increasing its resistance to bending/compression...ie...increasing its spring rate.

You cannot shorten a lever w/out changing its resistance to bending, unless another some other force is applied (ie...heat).

Now I'm sure someone like Stazi could throwm some engineering #s at you to support this idea.
