Not being a physics student and rather dense (yes, I admit it), will someone 
please explain what a "zero length spring" is?  I have searched on the net 
and found this law and that law, which means nothing to me.  Finally, I 
found a webpage that also called it a constant pressure spring and displayed 
a large heavy duty spring that wound around itself, much like an alarm clock 
spring.

It a zero length spring simply one that returns to its original shape after 
the force is released?

Thank you,
Gerald Payton
