In Reply to: SPRING RATE EQUATION - here it is... posted by TBR on June 28, 1999 at 14:32:43:
: ...
:
: K = w^4*G/8ND^3
: K = Spring stiffness (lbs/in)
: W = Wire Diameter
: G = Constant (12,000,000)
: N = number of active coils (no. of free coils + .5)
: D = coil diameter measured to wire centers
: This is a very sensitive equation - small errors in measurement will result in huge errors in the calculation. Good luck
