Red Bull RB8 Renault

I didn't see it closely (it was on at midnight our time) but could it have failed the matrix but not all of the fibers, so it still tensile capacity from the fibers on top of the nose but was able to move around more?

I suspect what we might be seeing is a kind of passive f-duct...

My guess is that it's designed to do this at speed:


Reducing the amount of air going under the nose, and hence reducing the amount of air flowing through the diffuser, and reducing drag. The benefit of course being that at slow speed, the diffuser can be designed to be incredibly downforcy, safe in the knowledge it's not going to be a huge penalty at high speed.

i dont know how we can draw conclusions from a car which has taken two hits on its front

I think we can draw conclussions about the nose cone when the car's taken two hits to the outside edge of the front wing.

haha, now i have spotted something just now!!
See the pic below its taken just before the pitstop
you can clearly see the mechanic who brings the new nose to replace
and look how he is carrying it around! he is holding the nose cone camera mount BUT it is intact!
which shows us that after running throught the DRS marker the nose cone and mount failed in vettel's car

someone here seems to have missed the race.

No, it shows us that the weight of a front wing is significantly less force on the nose cone than the force of a mechanic trying to wrestle it out of a set of tight mounting brackets. It also shows that when no twisting force is applied, no twisting occurs.

it has clearly hit the left sided mount, which would have ripped of its support

I don't believe the wing pilons are attached to that flexible material, but to the crash structure itself.

Before the hit, during the hit and after the hit
the middle pic you can see that mose cam has moved up during the impact....i will upload the video also, it will clear then
edit look post below

edit here is a better image


edit, the three images pic, please save the imaeg and enlarge it to see...i dont know how it became small

Gazzetta has a video showing some suspension stuff going on with RBR:

My Italian did not appear to be that good, but I intercepted removable shock absorber to find the correct ride height for setup, or something similar. I will appreciate if someone can shed some more light.

[siskue2005]

compare two pics, even with slight load the broken win mount twists, where as the top pic the mechanic carries the entire wing on the camera mount!
and the broken wing mechanic is not twisting, he just happened to put weight on the left side first and then the second, whereby he realises its broken and moves to other part to grab it

[antrock]

on the first picture the mechanic is holding the new nose - lets say it weighs 5 kilos. while the guy removing the old wing tries to lift and pull the nose while it is still attached to the car - few hundreds kilos! you can't compare the two.
