Anti-roll bars

[Vocal minority]

Does anyone have some formulae or know how to calculate the diameter of an anti-roll bar based on the width, length and type of bar/tube used?

Since I asked (By proxy - Bruce posted this using my login!)...

...I'll provide an answer myself:

Q=10⁴ x T² x k² x d⁴
________________
r² x L

Where T = Track (ins)
K = Fractional Lever arm ratio
(Movement at rollbar pickup)
____________________
(Movement at wheel)



d=bar diameter (ins)
r = effective arm length (ins)
l= half length of bar (ins)
Q= Stiffness of bar in lb/ins per degree of vehicle roll

Hope this helps!
