Does anyone know of any high res, good detail pics of cars with the nose removed, showing clearly the suspension.
I would especially like one of the FW14b.
Also does anyone know how to convert the G forces under heavy braking into Newtons.
Can it be done?
Much obliged

ok ok firstly we need to make a few assumptions:
1. Your in school, as in high school? Which grade?
If you want to convert between forces and accelerations, you use the good ol F=ma
So, from a global point of view the total breaking force would be something like (5g's acceleration):
F=ma
=650*4*9.81
=31 882N
I heard that 1g acceleration is due to the aerodynamics but i cant really confirm this.
Now the tricky bit is to know how much comes from where, how much of the total is applied to the suspension (front and rear) and how much comes from aero (of the breaking force).
If you want to know the total load on the suspension you have to include the moment that the breaks exert as well as the downforce that the wings provide. Sum the total vector forces after making a few guesses here and there and you should be in the right area.
I have no idea how much downforce there would be, naturally depends on speed. Hope some other people will be able to provide you with the info.
If I had to guess about the front/rear break force split it would be about 50:50 - i suppose. The rear wing is larger than the front, also you dont want to lock the rears so this is the reasoning behind the guess...
In the 3rd page of RacingManiac's album ALMS Motorsport 2005 ( http://supercarfreak.net/gallery/RacingManiac ) we can see an "extra rod" linked to the rocker arm of the suspension (picture PICT0046.jpg).
What's that rod for? Are the dumpers allowed to work just in traction (not in compression)?

It is for steering, that is a track rod. BTW, it is not "linked to the rocker arm of the suspension" but it only appears that way from the angle the pic was taken.

Donnington Museum was a very interesting place as you can follow these constructor by timeline. And you can see Aero takes a greater and greater role as detail like that tie-rod(trackrod) is moving from a more common trail steer(behind axle) and seperate plane from the a-arm to front steer, and shrud with the a-arm for aero.....and when they start using pushrod instead of pullrod...etc

Nice pics of the museum!
Is that rod inside the upper A-arm the rod that you are talking about?
