Glad to be of assistance. Seems anyone can appreciate the universal language of maths.

(I have since cleared some room in my inbox, btw, since your last PM to me filled it)

Grats Mike. Enjoy whatever little sleep you're having.

At least the increase in scrub radius would make it easier to park.

But not who you are.

I feel any thread which becomes a list of things people won't actually care about, for example what the weather in some random place in the world, and creates no conversation, is just a spam thread.

If the thread is a list but of something appreciated (a good photo or video thread, for example), or if people actually create conversation and don't just add their bit and never post again, then it's fine by me.

As TVE points out, any thread sufficiently derailed, or turning unpleasant, is fair target for the padlock too.

I were just too busy trying to beat up Bob

Trying being the operative word. I got the ball!

I think we've got the idea by now.

It was you who was doing most of the harrasing. Darling.

Quote from 1993weeman :

Also sorry to Bob Smith who i spun in front and he couldn't do anything about it except go straight into me for a head on crash.

Hey I'm sorry I hit you! Maybe I could have tried to drive around you rather than just brake as that clearly didn't help much. You were certainly far more bruised than I, but that may been from the next corner. Do you know what caused the brakes to fail? Brood managed to snap the cable in one of our karts.

Mike - we all want to see photos of you baby when the time comes now. Hopefully you won't plan any more little excursions in the next couple of weeks.

Split event talk off in to a new thread, as per usual. Sorry to anyone I might have offended on the chat Sat night, piss taking probably ran away with me. There is a reason I don't post while drunk!

Racing was good though, sadly there was a couple of slow karts but there's little you can do about that. Lots of close battles, some hard crashes, a couple of red flags (seems somebody accidently destroyed a tyre wall.... *whistles innocently*), gritter karts and even a flying karts (albeit briefly).

Nice to see so many friendly people, many regular faces and a few new ones too. Scandinavians are mostly mad. Great to see so many from abroad in general.

Thanks again to Jason for putting us up and all the bbq food. How I loved that chicken.

Damn early arrivals. Work is mad, only just leaving now (late rather than early!). See you all in 5 hours...

If I want to go down to the local shopping centre wearing bondage straps, a ski mask, and brandishing a chainsaw, I should have the right to do so. If I uncover the chainsaw, start it up, and begin hacking limbs off pensioners, then somebody should take action but not before.

Quote from Keling :

So, generally, in today's LFS, the tyres slip curves are too progressive and traction peaks are too high ( or too "late" ) ?

Maybe. Although looking at the peaks doesn't tell you enough, as you could change the peaks without changing the cornering or braking stiffnesses (especially in an empirical model).

First lets consider what's happening:

A locked diff does not ever permit tyres to rotate at different angular velocities. When driving round a corner in a car, the inside and outside wheels will travel different distances, so if they were allowed to free wheel, the inside wheel would rotate slower. Also weight transfer would put more load on the outside wheel, squishing it further, making the rolling radius smaller, further increasing the difference in free rolling angular velocities between inside and outside tyres.

As the wheels are not free rolling, this creates a slip ratio in the tyres when cornering. If no torque is being sent from the engine to the wheels, then this will be a negative slip ratio from the outside tyre (as it will be turning too slow), and a positive slip ratio from the inside tyre (it will be turning too fast).

These slip ratios create forces; how much depends on the braking stiffnesses of the two tyres (assuming the friction limit of the tyres is not breached). This force is negative for the outside wheel and positive for the inside wheel, these sum to create a torque in the opposite direction to that created by steering the car into the turn. So the car will not change direction as quickly, as the yaw torque will be reduced.

This reduction in yaw torque is the main reason cars are slower in tight bends with a locked diff (the smaller the radius of turn, the greater the proportion of the track width to turn radius, and thus the greatest slip ratios are produced when cornering).

So friction is not usually the limiting factor when it comes to tyre scrub caused by a locked diff, and even if it were wrong in LFS, it shouldn't be wrong by more than a few percent; not enough to explain the issues.

If the braking stiffness of the tyres was too low, however, the same slip ratios would give less longitudinal force, thus less yaw torque to slow the cars rotation, and thus less penalty for using one.

Braking stiffness is a very dynamic property, varing with load, tyre pressure, and slip angle, so my first point of suspicion would be that something is causing it to be too low.

Franky, admit it, you only want fel because he's fast. And looks like Nick Heidfeld.

Sorry but is there even any mod around anymore

Sorry I've been in training for the next kart meet. I've decided I can't possibly lose enough weight in time, so I'm currently high on a sugar binge, if I take enough my perception of time changes and I can do the race in bullet time, and then win with my superior Schumaker style steering corrections and lightning driver changes.

( Bob Smith , I want to know everything u know... )

I'll send you a postcard.

I'm closing this thread because:
a) This is an English language forum
b) This is not the GTR Evo or rFactor forums - LFS events only please!

The TVs in bars last night were watching the live stream of the "negotiations". I felt it was the next stage of reality TV; much like big brother with guns, nothing interesting was happening, the camera angles were poor, not enough lighting, and no script, and ugly dumb people.

What? On the internet? Perhaps there's hope for the human race yet!

I just went to www.lfs.net, logged in with my username and WEB password, clicked on account details, and I have the option to enter both new WEB and GAME passwords from that form.

Quote from Degats :

The tyres cool down after a few laps due to tyre wear - the tread thickness reduces, so becomes less insulating. In other words, the tread can't hold as much heat, so the tyres cool down quicker.

While true, this also means the tyre should also warm faster when generating heat (given the same energy input to the system).

In my own tyre heating model I have found that temperatures simply swing more as the tread wears, and if anything the average temperature continues to increase as the heat conducts deeper in to the carcass, sidewalls, and pressurised air, meaning less heat can be lost from the tread into these areas.

I don't see why the LFS model would differ from my own in this regard.

Well in that case we're going to have to guess what each other looks like...

You've not heard of emailing photographs then?

That looks really interesting, thanks. Sadly I've got a friend visiting that weekend and that's probably a bit far to drag him. It's not up north enough!

double digits for a 0-60 time is rather laughable, which is why I picked it.

What, 11 days? I would have thought you could reach it in well under a week.
