is there a reason for the a-symmetrical welding?

They are symmetrical. When you are talking about a radius, equally spaced is actually rotationally symmetrical.

Boy, oh boy! The brakes will have a tough time! I wonder how the Red Bull's will cope? They need more straight line speed, but at the same time the need the drag to ease the brakes!;)

In Monaco, they changed the rotors to ones the same as Ferrari use. Maybe they will use the same here too.

From F1.com

"In order to improve reliability following Sebastian Vettel's difficulties at the Spanish race, Red Bull have changed the RB6's brakes discs for the Monaco Grand Prix. They now feature smaller holes than the ones originally requested from brake supplier Brembo. During Thursday practice the team used the discs pictured, with small oval holes (red arrow), whereas for qualifying and the race the team opted for the same discs Ferrari use."

but they aren't equally spaced. Either it could be a coincidence or the geometry is dependant on driving direction.

Or maybe the welder could do 3 of the 4 welds without moving in this arrangement and then had to turn around to do the last one? Hopefully someone knows the true answer and can let us know!

Oh sorry you are correct, I was looking on my iPhone and saw things not there with the limited resolution.

It is notable that the covers are welded as well as bolted. Just as well, as the welding is minimal and not very tidy. If there was total reliance on this standard of welding, there would most likely be a problem in the race.

I'd say the bolts hold the manhole down, the welds are tell tales to verify it hasn't moved (for maintenance & security). You see a similar short welds on the routes used for civic events in London.

The Circuit Gilles Vileneuve has had new tarmac laid at the places where it broke up during its last Formula 1 event in 2008.

Turn two (the Senna hairpin), turns six and seven and turn ten (the Casino hairpin) all suffered a lot of damage during the qualifying session for the 2008 race.

They were patched up with quick-drying cement overnight but that didn’t prevent the problem recurring during the race. The track had also broken up in 2007.

Part of the problem is the harsh Canadian winter which weakens the tarmac. Past occasions when F1 races were been disrupted – even postponed – by tracks breaking up include the 1984 Dallas Grand Prix and 1985 Belgian Grand Prix.

The track also has new tarmac run-offs at turns six and eight for this year’s race.

I think that resurfacing is not good enough for the problem we saw over many years at the Senna hairpin. My understanding is that frost is getting into the deeper earth structures and pushes the tarmac up. If that is really the problem they can only cure this by digging the track up several feet deep and exchange the faulty earth with frost safe material.

Or alternitivly, concrete, as it is less likley to lift. But lifting the sections of faulty track by a few feet, then lay more "frost resistant" materials, then concrete and then good oild tar mac may be the best option. Even put under soil heating in those areas would be abetter resolve.

After Monaco, it was stated that there is a requirement by FIA that ALL manholes ae welded, and that bolting was not acceptable. I believe in belt and braces approach. If bolts can loosen, then the minimal welding shown in the photo, would not be adequate. Anyway, we'll just have to wait and see.

That is how I've seen them welded in every street race I've ever been to.

Anyone need any tix? I may have a some gen admin tix extra.

[strad]

I say that bumps, cracks etc. are a good thing. Hell give me a nice bump right on the perfect line. I like it when they have to drive around problems with the track. I still rue the day the teams were allowed to say the track wasn't smooth enough for their cars. They should have to build cars that suit the tracks,,not tracks that suit the cars.

Well that would explain what happened in Monaco, then!

Well, I hope that during the briefing some drivers will be reminded about the traffic light at the end of the pitlane.

Could rain be dangerous in Canada?













What is going on with drainage there?



Or we will have short brake for cleaning under SC condition?...
