How Are Under Weight F1 Cars Made Legal?

[Artwinter]

How are some of the highly financed F1 teams building there cars considerably under weight? But yet when they are weighed for the race they end up legal?

Don't they stick a load of ballast into the chassis?

(That or get Mansell in the car... )

You are partiially right but what kind of ballast is used and where is it actuall installed and what do they gain by using it?

Sorry Minardi Fan.

The ballst is a series of metallic weights in arcane highly dense metals, bolted low in the chassis to lower the center of gravity. I understand that the mounting locations vary from circuit to circuit as optimum balance is sought.

I believe that they are using depleted uranium. At least they did that a couple of years ago, and I remember some talking about this issue, since it is a highly expensive material. And alegedly health hazardous. They are placed at the lowest point at the car (I don’t have time right now to check my points, I’ll come back tomorrow, but I’m sure that the positions of the ballast are highly regulated) and the purpose is to alter the centre of gravity. Both in vertical plane (to make it as low as possible) and horizontal (helping for adjusting the car’s balance, the oversteering/understeering tendencies of the car. The first goal one is clear, make the CG it as low as possible; the later is adjusted during the friday/saturday/warm-up practice sessions as by driver’s requests.

Just a correction, not only the highly funded teams manage to make cars lighter that 600kg. Every one of them can do that; the difference is the amount of ballast that a team has to add (thus offering a greater flexibility and a more stable car)

A year or so ago I read an article that mcLaren was using Tungsten slugs in the wooden plank. This way they were adding weight as low as possible and could change the balance of the car as desired. It also lowered the center of gravit one inch. They also said that the cost of these Tungsten slugged planks was 160,000 pounds a year.I have to admit that they have some great engineers in F1.

Depleted Uranium (DU) is used primarily in weaponry as a denser substitute for lead. Here is a faq from http://www.gulflink.osd.mil/faq_17apr.htm

Q. What makes depleted uranium a potential hazard?

A. Depleted uranium is a heavy metal that is also slightly radioactive. Heavy metals (uranium, lead, tungsten, etc.) have chemical toxicity properties that, in high doses, can cause adverse health effects. Depleted uranium that remains outside the body can not harm you.

A common misconception is that radiation is depleted uranium's primary hazard. This is not the case under most battlefield exposure scenarios. Depleted uranium is approximately 40 percent less radioactive than natural uranium. Depleted uranium emits alpha and beta particles, and gamma rays. Alpha particles, the primary radiation type produced by depleted uranium, are blocked by skin, while beta particles are blocked by the boots and battle dress utility uniform (BDUs) typically worn by service members. While gamma rays are a form of highly-penetrating energy , the amount of gamma radiation emitted by depleted uranium is very low. Thus, depleted uranium does not significantly add to the background radiation
that we encounter every day.

A team was also looking at using a form of hydraulic system to push liquid around the car so provide the optimum handling in every corner of a track (sound like the active suspension days), currently the just use static weights as was mentioned. But the FIA quashed the idea because of the costs and the potential danger of superheated liquid burning mechanics. I do not remember where I read or this so I hope someone can back me up. Also To gain extra weight in the car Johnny Herbert used to **** in his cockpit

[Red]

Yep, that’s why I said allegedly. Unlike the ammunition, the ballast does not explode or otherwise spread small particles all around. It’s much like the Be-alloys affaire. Beryllium (or its oxides) could be toxic; if swallowed, inhaled...

Champ, now THAT would be some “active ballancing”

[Valve Bounce]

Oh! Poo!!! :confused: :confused: :confused: (that's my smelly smilie) , and that can have a distinct effect on the dirty air for following cars.

[Champ69]

My message was censored. The **** was pea. I have read a few stories about drivers peaing in their cars. Apparently Johnny Herbert was one of the worst. The funniest one was when one of the Stewart mechanics was trying to find out what a strange liquid was coming out of Johnny’s car on the pre-grid only to find out it was urine.

Jacky to Johnny: “pit on lap 28 for fuel, tyre and nappy change”

????????????????????????????????????

[Total-F1]

Yeah - well known strange piece of F1 information - Johnny Herbert always used to pee in the car on the grid before a race...

[EERO]

...Things I wish I didn't know....:confused:

[Alan Jones]

Which is why when interviewed with questions like, " How did it go today Johnny? "

"Really good Louise, we ****ed it in"

[DNQ]

Hmm, I agree with Eero on this one..

[eatapc]

I wonder if Ralf Kelleners and Didier Theys knew this when they teamed up with Herbert for the 24 hours of LeMans? Would you want to be Johnny's co-driver?

[Artwinter]

Why don't you guys quit being arse holes and stick to the subject?

[JeremySmith]

Art please refrain from calling our posters...Well you know! Calm down have a nice cup of tea..

[Alan Jones]

Art,
you were a lot nicer when you were Gwen

[Artwinter]

Alan Jones.

Nuthing personal against you. But there was no reason turning a good post into a driver urinating in the car. Don't you think it was rather childish?

[Alan Jones]

To be honest Art, I thought it was an interesting piece of trivia and I actually found it rather amusing,which is why I come here so often.
The chance to talk F1 and have a giggle with some likeminded people is a good break from the reality of everyday life. I'm sure Champ69 posted with the same attitude, he didn't want to wreck your thread, just thought he'd share something amusing with us all.

Many threads deviate from the original topic which is normal, the same thing happens in conversations between people all over the world. You Know, one thing leads to another......

All the best Art, if your thread goes off track, give it a gentle nudge back, and away you go again. Keep Smilin'

[Bononi]

Is there any kind of reservatory for that thing ?

And... hey... they should do some kind of anti-doping in the drivers...

...some driver's liquid can be inflammable !!

[Artwinter]

Bononi.

Yes they call it a urnal. What do you want Porta Potties in each car? I can see them now pulling a trailor with an out house on it. Which would slow the cars down.
