Hello Jerry,

A normal screen door spring is a "zero lenght spring" it is made be twisting 
the wire as the spring is wound.  The screen door spring would be shorter if 
it's own coils didn't get in the way.

Zero lenght = constant force = Its force is proportional to its entire 
length, not just the stretched length, and its force is therefore constant 
over the range of flexures in which the spring is elastic

Hello Jerry,

A normal screen door spring is a =

Zero lenght =3D constant force =3D Its force is proportional =

entire length, not just the stretched length, and its force is therefore =

elastic
