Re: math class needed on valve springs
If you can find a comparable spring on the PAC Racing site, this link to their spring rate calculator might help.

Re: math class needed on valve springs
The basic formula is F=kX . F is the force , k is the rate , X is the difference in spring height from the length of the spring when it is not loaded .

Re: math class needed on valve springs
Quote:
To add to above, the spring rate is stated as the force generated per unit of compression. Ex: 1,000 Lbf/Inch, 1,700 N/cm etc. Also, its spring FORCE, not pressure. Spring pressure is a common misnomer racers seem to always use, and it just wont die. Its entirely wrong. Its not a pressure, Its a force. |
