Forward mass distribution does lead to understeer, all other things being equal.

Forward load transfer leads to oversteer, all other things being equal.

And no, I doubt they misjudged something as simple as that.

Does the same apply in reverse?

Rearward mass = oversteer
Rearward weight transfer = understeer

?

Also you may be able to help on this post...

Little bit off topic, but related to an earlier post:

Everyone is jumping on Hamilton's comments at this time last year, but if memory serves they ran the first tests with the 2008 wings on the cars and the car actually looked good and was near the front of the field. It was only at the second test onwards that they ran their new 2009 wings and the problems and visible panic appeared.

You & I seem to be the only ones that remember that... I was gonna go back to the MP4/24 thread to confirm, but it was late

changing weight distribution is actually quite easy(especially on these cars), and moreso this yera with the 15 extra kg of ballast and no more KERS.

I really doubt it will be easier this year because of the additional 70 to 90 variable fuel load to deal with.

Doubt whatever you want but you will still be wrong.

the carsmass distribution is very easy to change.

You can move ballast around or you can move the whole car around between the wheels by alterng the suspension members.

Without knowing how the car will perform on the 2010 spec tyres, its conceivable that Merc have designed different suspension geometries to allow for shifting the mass balance around the wheels. We'll onlyknow in a weeks time once they have revised the car. then we'll have some insight into their design philosophy.

it is highly likely that Ferrari has struck it lucky and achieved the ideal balance immediately, perhaps thei closer relationship to Bridgestone has helped them here...[opens can of worms]

yep

Didn't KERS weigh something like 29kg or so? With Williams developing their flywheel one which would've done it in 19 or 15 kgs? I can't remember exact figures though...

Merc system was 25kgs... whereas the williams was around 35kgs, they couldnt get it lower and thats what held it out... but even at 35 kgs, if it was unlimited they would have slapped it on there no doubt.

Thinking from a scientific perspective, there must be some playoff between mass and momentum. The extra mass will increase the friction of the front wheels improving turning force, but if it is far from the centre of mass then will also provide a moment resisting the change of direction. Seems like some sort of a mechanics problem.

With an 08' rear wing.....

Excellent interview with Ross Brawn..

http://news.bbc.co.uk/sport1/hi/motorsp ... 497949.stm

The car has handling imbalance, is as fast as Ferrari on full tanks, but not when running empty & they are cracking exhausts every 100-200km.

That was not in the linked interview. The link was about the points system and tyres. Can you add the correct source for your intelligence on the W01.

[ben_watkins]

If you play the video of RB, the first few minutes he talks about the car.. the final few mins are on the new points system............

another link to the same video interview on it's own

Worth noting that the video is only available in the UK, so not everyone might be able to see that

Right I see, so maybe you guys outside the UK need a nice UK proxy to see the video...

[ISLAMATRON]

care to provide us with one?

[Giblet]

Proxies that work reliably or for more than one day are a rare breed. But paying for one is a cheap solution, and reliable.

There is no frikkin way I am going to deal with Justin.tv again this year to watch stuff that is not broadcast, unless I absolutely have to. If you find a good pay proxy that is cheap and can run the BBC player, please pass on the provider.

found a link to the Brawn interview

[ben_watkins]

a quick google for UK Proxy threw up a few answers..

I didn't know Michael also tested one of the Schuberth 2010 prototype helmets.

The Ross Brawn interview is quoted in the 2010 testing thread.
