2011 F1 Regs - In Pictures

3.17.5 Bodywork may deflect no more than 5mm vertically when a 2000N load is applied vertically to it at three different points which lie on the car centre line and 100mm either side of it. Each of these loads will be applied in an upward direction at a point 380mm rearward of the front wheel centre line using a 50mm diameter ram in the two outer locations and a 70mm diameter ram on the car centre line. Stays or structures between the front of the bodywork lying on the reference plane and the survival cell may be present for this test, provided they are completely rigid and have no system or mechanism which allows non-linear deflection during any part of the test.
Furthermore, the bodywork being tested in this area may not include any component which is capable of allowing more than the permitted amount of deflection under the test load (including any linear deflection above the test load), such components could include, but are not limited to:
Joints, bearings pivots or any other form of articulation.
Dampers, hydraulics or any form of time dependent component or structure.
Buckling members or any component or design which may have, or is suspected of having, any non-linear characteristics.
Any parts which may systematically or routinely exhibit permanent deformation.
This is how the Red Bull managed to be so quick, it used an upward flexing floor assembly, upward flex wasn't tested for in the 2010 regs, only a load was applied to check for flexing downwards. This allowed the Red Bull to run the front of the chassis on the ground under aero load, without unloading the suspension, this lowered the front wing height and improved ground effect, it also gave a reduced diasadvantage for the setup changes that occured as the weight came off as the fuel burned during the race.Furthermore, the bodywork being tested in this area may not include any component which is capable of allowing more than the permitted amount of deflection under the test load (including any linear deflection above the test load), such components could include, but are not limited to:

Dampers, hydraulics or any form of time dependent component or structure.
Buckling members or any component or design which may have, or is suspected of having, any non-linear characteristics.
Any parts which may systematically or routinely exhibit permanent deformation.
So there goes the big Red Bull advantage for next years cars, McLaren and Ferrari will be back in the fight, unless of course Adrian comes up with another gem.

Looking forward to the 4pot's for 2012 just to see how they work with them.
