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 08M) Given a free length of.750" and a rate of 22 pounds per inch, find the load at.500" working length. P = 22 x ( ) = 22 x.250 = 5.5lbs. 2. 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 01M) 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 ( )] +.7 = (6.9 x.500) +.7 = = 4.15 lbs.
