OK, I have another question about one of the formulas.
"Front Roll Couple = (Torsion bar wheel rate * 2) + front sway bar wheel rate"
I see that it's torsion bar wheel rate times 2.
I imagine that's because there are two torsion bars & two wheels.
That makes sense.
I see that it's front sway bar wheel rate.
That's the sway bar rate for a single front wheel.
Since there are two front wheels, should it be front sway bar wheel rate times 2?
Front Sway Bar wheel rate Opt 2 = sway bar rate * (Motion Ratio^2)
Leaf spring wheel rate = (listed rate) * (Motion Ratio^2) * 2
These two formulas are both supposed to determine the wheel rate.
They both have spring rate times motion ratio squared.
Yet one of the formulas has a x2, and the other doesn't.
Why aren't these formulas the same if they're doing the same thing?
It seems like the *2 at the end of the Leaf Spring Wheel Rate Formula shouldn't be there.
Using 70 B body as an example, distance between leaf spring perches is 44 inches, divided by track width of 59.2 inches = .7432432 motion ratio.
that motion ratio squared is .5524104
multiplied by a 160 pound spring rate = 88.38566
then when you multiply that by 2, you get 176.77132
It seems odd that the wheel rate would be higher than the spring rate.
