Re: 75 Modifications - What have u done?
Afraid the statement in the last post " 27mm bent frontstabilizer (as stiff as a32mm welded one)" is what used to be called "a common misconception".
The stiffness of an anti-roll bar (stabiliser bar) depends only on two things; one is the Modulus of Elasticity of the material, and the other is the diameter of the bar (the calculation uses the 4th power of the diameter to work out the stiffness). The standard engineering calculation shows that a 32mm bar would be almost twice as stiff as a 27mm bar!(the effect of the 4th power).
The arms of the bar should be regarded as lever arms which apply torque to the bar and how they are formed or attached makes no difference, given that they are of sufficiently large section not to bend themselves, and, if welded on, the welds are sufficiently strong not to shear: - easily calculated using standard formulae for Stress & Strain.
(For interest, arms fabricated from standard 8x50mm steel would be 3 times stiffer than the arms formed by bending 27mm bar; in other words, a fabricated 27mm bar would be "stiffer" than a bent one.)
If the 27mm bent bar really was much stiffer than a 32mm fabricated bar then something else was changed; either the larger bar was hollow (a tube, in which case the formula uses both the inside and outside diameters to the 4th power); one of the bars wasn't steel; front spring and/or rear spring rates were changed, rear bar was changed, or some other changes were made.
Fabrication is a perfectly acceptable, and often a better way of making antiroll bars; it's been normal practice in F1 for years, and in many other high load, high stress applications.
And just to add to the above which I was about to point out as well...

Just kidding as most of that went over my head anyway but a good read
