Hi Ted,

       'k' is the force constant of the spring in say, pounds per inch of 
stretch. This is constant until you get to very large extensions which change the 
spiral.

       An example of a zero length spring is an ordinary clock spring when 
you pull it along it's shaft axis. 

       Regards,
