Suspension Diagrams - Workings

I'm gonna discuss how my Suspension Diagram program works in this post. Brace yourself for maths!

Suspension diagrams

In my venture to learn more about vehicle dynamics, and apply that knowledge to racing simulators, I found the need for some fairly intimate analysis of the cars. The characteristics of the suspension are affected by a lot of things. For instance, in an Endurance Series DBR9, the default front spring rate of 245n/mm translates to a 'wheel rate' of 133n/mm when measured at the wheel. This is due to various factors in the suspension geometry. I figured this would be helpful to understand on a car-by-car basis, so I'm working on a program to draw diagrams of the suspension geometry on these cars. Read on for more info.
