Spring Cutting

[pvtschultz]

The springs in our cars do not twist at all under compression. A spring that is rated at 300# will be 300# no matter how much you cut our of it, and will compress 1 inch for every 300 pounds that is added to it. The formula is y=kx, where k is the spring constant. So if you cut a coil out of your springs, it is still going to have the same spring constant, it will still COMPRESS the same amount, you will just bottom out at a lighter FORCE. NO TWISTING

Sigh. Ok, you sucked me in (musta been the capital letters). The problem with your formula is that k, the "spring constant" is only constant for a particular spring. It is not constant if you cut coils out. The equation for a coil spring is:


k = [1,500,000 X d(to the fourth power)] divided by [n X D(cubed)]

d is the diameter of the spring wire, n is the number of coils, D is the diameter of the coils. Decrease n and k goes up accordingly.

This web site spells it all out:

This web site has the formula and is also a spring constant calculator.

And the spring wire does twist :D .

how many times do we have to say it..i rode in the car numerous times before the cut and i rode in it after and there is no difference at all..NONE

dont be so closed minded to think that cutting 1 coil i going to make your car ride like azz
