2014 F1 Season.

I don’t know but I would guess that Alexander Rossi is driving for Marussia this weekend. Isn’t he the test driver (3^rd driver) for Marussia? I think that he also is a test driver for Caterham…

Brit Will Stevens was also appointed as a reserve driver last week, but of course he hasn't even driven the car yet.

Didn't he have 'paperwork problems'?

Yes, unbelievably in this day and age his Super licence paper work was lost/delayed, by DHL apparently.

It is sanctioned by the FIA but they had to see a paper copy original of the paper work they issued  apparently.

One alternative could off course be to use some previous F1-driver with a lot of experience, such as Paul di Resta or maybe Heikki Kovalainen.

If a “bigger” team would have been in this situation that would have been my guess but I find this unlikely for Marussia.

They have economic trouble and probably not the cash to employ an experienced driver.

If they can get a driver to pay for the “seat” they will probably go for the one that’s paying the most, if they do not go with Rossi.

Only speculation off course…  I guess that it will be announced soon…

Marussia are preparing "Jules" car but as yet no announcement as to who if anyone will drive it.

I guess that they will have much work ahead of them in rebuilding the car. Will they make it?

One option could be to only run with one car this weekend I guess.

I also had a thought that maybe they will not run at all to honor Bianchi. To do this I guess that they need to clear this with FIA.

From what you wright BigH47 it looks like they are aiming to run both cars. That’s good to hear!

There is the possibility of fines if they fail to operate 2 cars, unless of course "force majure" is applied.

Repairs to the car should be well within Marussia's  capabilities , probably a new chassis(tub) will be needed. 

There is no such thing as a centrifugal force. What is acting is the grip of the tyres allowing the corner to be made, providing the Centripetal Force - the tyres provide a Friction Force. Without the Centripetal Force provided by the Friction of the tyres on the surface all that is left is Inertia, which when opposed by other normal Friction Forces, results in negative acceleration - what some might call deceleration. Inertia can only result in no negative acceleration in the absence of Gravitational Forces in a Perfect Vacuum, thus removing normal air drag with no mechanical Friction ...

Otherwise we have solved all energy requirements for Eternity, and I can promise you that we have not. Energy for Force and therefore acceleration can only be exchanged, and not created afresh ...

Force = Acceleration x Mass. [Newton again]. Completely peer reviewed by now, and, unlike Dawinsim, not a subject of current doubt.

ATB from George

Scientifically speaking, the acceleration of any object on a curved trajectory is constantly changing.

In the case of a motor vehicle, and of a racing car in particular, the forces trying to make it fly off at a tangent (whether you call it centrifugal or centripetal force) are resisted, mainly, by the tyres.

These resist the c-force through friction which also deforms the tyre wall. This must absorb some energy similar to compressing a spring. This keeps the car on its curved path.

If that frictional energy disappears, as in aquaplaning, the energy must go somewhere. It is quite conceivable that it turns into tangential velocity. it won't last long because other frictional forces will build so perpetual motion is not suggested.

The 130 R corner at Suzuka is a classic example. In the dry cars enter at maximum revs and speed. During the corner the force required to keep the car on line causes the cars to lose speed despite being on full throttle.

Hilarious how a simple statement of a known and measurable effect, which may or may not have happened,  can result in extrapolation past the concept of perpetual motion. Forums huh?! Good laugh though and somewhat of a relief after such a grim event.

Gets the old grey matter churning. Isn't this why we accelerate into and out of a corner. Haven't we all experienced deceleration while going round a roundabout, try keeping the same speed you enter a long corner or roundabout during and then out of that same curve. 

Also in the old days before brakes could grab the disks when they locked at the point of pressing the pedal hard, you lost control, it felt the car is then gaining new forces forward and you instinctively knew it was bad as the speed was somehow maintained?

Just guessing mind .....

Hi BigH47!

When I wrote “they need to clear this with FIA” I meant to avoid fines. So we are of the same opinion here I think

I also think that they need a new chassis. That was why I’m a bit worried that they may not have a second car ready in time. I heard that it would take a lot of time to ship a new chassis to Russia and now with race two weekends in a row it could be very hard to finish the rebuild of the second car.

When you wright “Repairs to the car should be well within Marussia's capabilities” do you have any additional information? Is a new chassis shipped and will it arrive in good time before the race-weekend i.e today I guess…

It would be nice if they can have two cars for their home GP...

/Marcus

Marcus I know that some teams will actually have a spare tub with them, whether that applies to "fly aways", but if you can get a CD from  the other side of the planet in a day getting one from the UK shouldn't be a problem.

Alexander Rossi (#42) is in the Marussia this weekend BTW.

BigH47, I agree with you that you often can ship different things quite fast. The problem and most time consuming part of shipping is often to clear customs (from my experience). That can take hours, several days or even weeks.

I never shipped anything to Russia but I have shipped car parts to Australia, US and other countries. Sometimes it has taken 3 weeks for items to arrive in US (when sent from Sweden). When checking where the parts are you gets the answer “it’s waiting to clear customs”.

Perhaps F1-teams have a “VIP-line” through customs but I doubt it. Authorities hardly ever care if you are in a hurry or not…

I read that Marussia will race with only one car this weekend. I had a feeling this would be the case. If it’s because shortage in car parts or chassis, lack of money or to honor Bianchi, I don’t know. I hope for the latter…

/Marcus

Obviously F1 teams are capable of clearing customs. Otherwise they wouldn't be able to race at all this weekend. Everything will have shipped from Japan on Monday this week.

Marussia have a fully ready car with number 17 on it. They are choosing not to race it out of respect for Jules.

Yes, obviously all teams will race in Russia…

I’m not an expert of how it works for different items to clear customs. I read that this was a major concern if a chassis would be shipped from UK to Russia. I thought that this made sense and it’s also a personal experience of mine. Why does it take three weeks to send for example a catalytic converter to US…? Why could that not happen to a chassis sent from UK to Russia…? Please enlighten me!!

I think that there is a difference between sending a specific item and the “Formula 1 circus” traveling around. Don’t you think?

There are no forces making the car want to go straight (or "fly off at a tangent"). The forces the car experiences are the forces that make it turn (you are correct that turning is a from of acceleration. The direction of the velocity vector is being changed, even if its magnitude is not).

There is no such thing as "frictional energy". Friction (if there is sliding) turns kinetic energy into heat. Yes, it is more complicated with tyres that deform and can perhaps store some energy as "springs", but to suggest that this can accelerate an aquaplaning car is a fair stretch.

Forgive my terminology. Any moving object wants to continue in its direction so it does want to go straight which is why it takes force/energy to deviate it from its path.

I agree that most energy in a trye used to change direction is heat but, when that energy is not used, as in aquaplaning, to provide a turning force where does it go?

The energy converted to heat due to friction when sliding slightly through a normal turn doesn't do anything except make things (tyres and track surface) hotter. You don't somehow get it back when you stop turning or go into a fill-on slide.

Turning itself needs force, but doesn't actually require much energy because you are only changing direction, rather than getting faster. The force is applied at right angles to the velocity vector so doesn't change kinetic energy (unlike forces due to engine and brakes which apply parallel to the velocity vector). You may need to add in some energy with the throttle to make up for the extra losses due to the tyres scrubbing and heating but this is fairly minor. That energy however is "gone" and doesn't contribute to any acceleration as the car straightens out (due to straightening of steering or skidding/aquaplaning).

That Russian GP has to be the dullest of the season so far, a great cure for insomnia.

Good win for Lewis and Mercedes taking the constructor's and Jenson did well but it was till a yawn, Rosberg's progress not withstanding.

It was not the most exciting race of the season but it was worth if anything just by watching two big egos sitting side by side discussing world domination.

 " I wonder if it it uses plutonium as ink?"

Some people say that tyres should be more durable so that the drivers can just race. But now you see what you would get for every race.

Don't you mean Polonium?

OR: "Just sign the contract in blood as we agreed, Mr Eccleston"
