Wut.

My internet is too slow

Thanks

Anyone got a stream?

I think you can just keep pressing shift-g in game until "Gear Select: Shifter" comes up or something like that.

EDIT: Might be ctrl-g actually.

As much as I hate him as a person, he is an amazingly good racing driver. Deserves to be at the top of the standings. Not sure actually how bad the Ferrari is given how relatively well Massa did.

Yesssssss.

Perez: "He has no respect for other drivers - he didn't give me any room. Very stupid driver"

He's not happy.

Need to see a Maldonado on-board, but looked like his fault from the outside. Perez left him plenty of room.

Maldonado AGAIN!!!!!!

Michael, Felipe is faster than you.

Kudos to Eoin there, thought he did a very good job on comms Although when he says "ooooooooh" he sounds exactly the same as Phil Diaz.

That's practice, no?

This is a typical cross-section of an F1 wing:



As you can see it's pretty damn similar to the cross-section of the aeroplane wing above, but the other way around (as would be expected). Hence we can use the same analysis of this F1 wing as we can an aeroplane wing

The equation used to work out the amount of lift is L = V * density * circulation. If you have a 2D cylinder travelling at a certain speed, it will produce no lift. However if you add a small trailing edge (like a little notch in the bottom right hand corner) then the system will start to produce some lift. This is because a theorem states that when there is a sharp trailing edge in a system, the system itself will induce a certain amount of circulation (kind of like air moving in a circular motion) to keep a stagnation point at the trailing edge. That's why you get lift. If you extend the trailing edge to more of a wing-type shape then you get more lift produced.

If we flip it around and instead put the trailing edge at the front (akin to going backwards) then our actual trailing edge (which is the round bit) is no longer a sharp point, and our theorem above no longer applies. Hence not much (if any - I'm not 100% sure exactly) circulation is produced by the system, and by reference to the above equation it can be seen that very little if any lift will be produced at any speed.

To flip the whole system upside down, it means you'll get downforce going forwards but practically none, if any, going backwards.

So yes, LFS is correct.

If it works on NASCAR, why won't on Single Seaters?

Because in that case, the entire car is acting like a wing - if you raise the car off the ground, the car looks exactly like a wing (relatively flat bottom, curved top) and so produces lots of lift. See Mark Webber @ Le Mans, that one at Road Atlanta and so forth.

Quote from DANIEL-CRO :

I don't get it. Look pic:
On pic down you can clearly see that higher pressure is under wing, which should give some lift.

Quote from tristancliffe :

The angle of attack has little to do with it (more to do with drag). The profile of the wing is what causes lift (downforce), and that will work properly only in the forwards direction. Backwards won't cause lift (although air under the car itself might)

Yes Tristan is right - even in reverse the top surface is curved compared to the bottom which means you're definitely not going to get any downward force (lift in the case of the car). The reason you get very little lift (when you reverse it) is because your trailing edge is curved. You need a sharp trailing edge to produce any decent amount of lift.

EDIT: And in your first picture you're going to get a very large amount of turbulence produced and the wing would quite probably have stalled at that angle of attack.

That's not how it works. If you turned the wings upside down then you would get lift. If you go in reverse you will get a negligible amount of downforce, and definitely no lift. The lower pressure is still on the underside of the wing whichever direction you travel in.

So are Arsenal technically a 0-man team now? So worse than Rangers?

so ****ing nice for night driving in your car. especially in summer. I love it so much that I have a problem to actually leave the car and go to my flat. viva la audio system.

I'm not a massive fan of the original song (it's ok) and normally I absolutely hate mixes like that, but that's actually pretty damn good!!

Quote from dekojester :

No verbal spotter application in the history of LFS has proven to be reliable, things happen too quickly for it to keep up. I know Aonio can give a visual "radar" reference, but I haven't used it and haven't heard enough to know if it'd be useful. There's also no real way to know people are using it, so I can't mandate its use. I supose Airio knows Aonio runs (I'm fairly confident certian information in Airio is only shown if that user has Aonio running to relay it to Airio). However, I refuse to run Airio during a race session, it can cause too many issues.

It's not massively useful. To actually get any use out of it you actually have to look at it, rather than it being in the "corner of your eye", so to speak, but then your eyes aren't on the road. It's perhaps useful to see how many people are drafting behind you, but not as a quick reference to see how many people are underneath you. The race is too quick for that.

And yes JP I was being sarcastic

Quote from CodeLyoko1 :

You need a spotter you can trust.

I certainly wouldn't trust anyone short of a professional spotter to actually do it right. If deko wants to pay for one for everyone then go for it

During the race I was watching Matt and seeing how easy it would be to be a spotter. It's practically impossible as you're shouting instructions continually.

Quote from CodeLyoko1 :

how about spotters next year

But my spotter said I was clear11!!!11!!

EDIT: To slightly expand, if I used a spotter, he says "clear", and I turn into someone, who gets the punishment? I do.
