  COMPRESSION SPRINGS
  To find the load at any working length, when free length
  and rate are given, use the formula:  P = R x F
  where P is the load in lbs.; R is the rate in lbs. per 
  inch; F is the  deflection from free length.
    Example: (Lee Stock Spring Catalog #LC-032C-8)  Given 
	a free length of .750 and a rate of 22 pounds per 
	inch, 	find the load at 1/2 working length.
       P = 22 x .250 = 5.5lbs.
  EXTENSION SPRINGS
  To find the load at any working length,  when the free 
  length, rate and initial tension are given, use the 
  formula:  P= (R x F) + I.T.
  where P is the load in lbs.; R is the rate in lbs. per inch;
  F is the deflection from free length; I.T. is the initial 
  tension.
     Example: (Lee Stock Spring Catalog #LE-031C-1)  Given a
     free length of 1, a rate of 6.9 pounds per inch, and 
	 .7 pounds initial tension, find the load at 1.500.
      P = (6.9 x .500) + .7 = 3.45 + .7 = 4.15 lbs.
