Button needs to finish on the podium for all of the six remaining races to guarantee winning the championship.

Of course, that's assuming Rubens wins all the remaining races, which he is highly unlikely to do. So realistically I think another 3 or 4 podium finishes should pretty much wrap it up for Button.

Quote from Intrepid :Depends who's doing it!

Quote from 5haz :Quite right, depends on who you're squeezing, squeeze the wrong person and you'll be on the recieving end of a slap.

Don't think that is what Intrepid was trying to say exactly, (well not just that maybe).

Quote from keiran :Technically it's twice, your allowed to move once to defend and then you're allowed to move back to the racing line.

Well however many times it is, that particular ruling is about unsporting "blocking" whilst in front of the other car.

I'm asking in what way and when is squeezing a car out, (ie giving them the option of either braking or getting run off the circuit to avoid contact), when beside them ever legitimate??

I'm not talking about drivers attempting overtaking in to gaps that they know full well are diminishing due to the normal racing line of the driver in front. I'm refering to the movement across a straight section of the track of one driver whilst substantially overlapped with another in order to force them to "back off" or end up off the track.

Wasn't sporting when Hamilton did it to Webber, so I don't see how it was when Vettel did it to Button. And no I don't see it as a matter of degrees. To my mind unless you are fully infront of the car in question and it can be considered a legitmate blocking move, it's not acceptable behaviour.

Quote from Mikkomattic :I know that the behaviour I described in my big post was essentially correct, but the physical explanation might be lacking or wrong. I want to know the exact truth more specifically, so here's the question. Try to answer as briefly and layman-ish as possible (so that I might pass it along to non physics majors)

What causes the wheels to be harder to lock up the faster you are going?

Due to the higher energies involved at higher speeds the brakes can't generate the required deceleration in the wheel to cause the tyres to loose grip. Any brake system has a maximum amount of frictional force it can produce. At higher speeds this means the brakes just don't produce enough force to slow the wheel down quickly enough to cause the wheel to lock.

It's as simple as that in laymans terms.

Quote from Klutch :The T-Virus is an infection.


I suppose Resident evil isn't a real zombie movie?

In 28 Days later they haven't died. They are living humans with an infection that makes them extremely aggressive, more akin to rabid dogs.

Definition of Zombie is the "living dead" ie they must be dead. In 28 Days later they are not dead, just infected. Eventually they starve to death and die and no longer walk around attacking people. QED they are not Zombies.

In Resident evil, they were killed by an infection but attacked people whilst dead. QED they are Zombies.

Well, to be honest MS only really have themselves to blame. If they hadn't had such dubious business practices over the last two decades this kind of action would probably have been laughed out of court. Simple fact is MS have been proven to have had a complete disregard for anti-competitive practice legislation in the past and have shown very little restraint as to how far they are willing to go to kill competition. QED no body trusts them to do the right thing and public opinion is generally against them.

You make your bed, you lie in it.

If we're now talking 2D all you need to do is take your known vector equation transform it through 90 degrees and then you'll have the vector equation for the line between the points P1 and P2. From there given your known co-ordinates at P and the distances X and Y you should be able to calculate the co-ords for P1 and P2.

I think

Quote from MAD3.0LT :yer 100kgs is a bit much i personaly dont think a f1 driver dose that for a entier race lol i leg press 170kgs at the gym and no fing way in hell am i going to be able to do more then 5 sets of 10 even though i dont do it like that

i couldnt see it being 100kgs tbh

If you leg press 170kg, you should know how much easier it is to calf raise 170kg then. Dont forget the ROM and the leverages involved in the two exersizes. 100kg of pressure with the calf isn't as huge as people think in all honesty.

As for the G-Force question.. Well the drivers are very well strapped in, but their foot can obviously still rotate around the ankle joint. Foot n boot probably does weigh a couple of Kg maybe, so even if they were hitting 5g deceleration that's still only an extra 10kg on the brake pedal. Not a whole lot compared to 100kg really.

Plus, I'm willing to put money on that 100kg figure being a transient "peak" figure off the telemetry, not a sustained pressure over several seconds.

Quote from george_tsiros :you couldn't even spell the name

you want me to believe you know anything about them?

That's a rather pathetic thing to say in all honesty.

Quote :
86db/w/m at 6Ω with max power 75W?

my farts have more low end than that.

The overall sensitivity, impedance and power handling figures of a speaker tells you absolutely nothing about their "low end" performance.

Diamonds are tiny speakers of course they don't have low end. Show me a £300 speaker that can do low with anything resembling accuracy or control?? I'd rather not have it, than have a load of waffle.

Quote :
and yeah, i've seen wharfedales. their construction (unless it has improved thousandfold the past 10 years) reminds me of lego.

Uhuh, care to point me to a pair of £300 speakers that are better constructed? Bigger they may be, thicker cabinets they may have, but vastly more prone to cabinet resonances they also are, and hence a lot more in need of high quality cabinet construction and materials. Trust me, you're going to be listening to a lot more cabinet resonance from an average pair of £300 speakers than you are with the Diamonds.

Anyway, I'm not going to discuss it further. I don't take kindly to being called stupid over a pathetic point of a spelling mistake. Let's just say that I have designed and built, (several variations), of my own speakers in the past, so I know something about what it takes to make good ones.

Alternative to Bobs suggestion. Same budget :


Amp £170 : Cambridge Audio Azure 640a V2

Reviewed as being better than most sub £500 amps - of course it's a matter of opinion to some extent.

Speakers £80 : Tannoy Mercury F1 Custom

A steal at the price RRP is £160 and review well at that price point.

"If you've seen our Awards 2007 issue, then you'll know that these Tannoy Mercury F1 Customs are among our favourite speakers up to £160. Which leaves only one conclusion: the Tannoys are still the best budget speakers around. Which means this review is destined to be something of a lap of honour."

Quote from george_tsiros :so since you understand why i gave that split, why did you say the previous things?

a 70gbp set of speakers will rattle and resonate badly (needing 50gbp in stands) because... brace for it... they are 70gbp worth of speakers and their enclosure will suck!!!

if you can't spend 150 on a set of speakers (entry level KEF/AE or whatever floats around this year) you aren't talking about a "hifi" set. you're talking about a glorified pc speaker set.

instead of 300 for a system that has 70 worth of speakers (the most sensitive component of audio and the second most important aspect of sound reproduction that is actually under your control) get a selfpowered set of speakers and a high quality, external, sound card.

wtf

70gbp for speakers

my 5.1 logitech set of crap was that much

spending 150 on an amp to drive 70 worth of speakers?

that's just plain wrong resource management.

Have you ever seen, let alone handled or listened to Warfdale Diamonds??

Your response suggests you haven't. I think you'll be surprised. They have won many awards over the years and comparing them with PC speakers is, to be blunt, ludicrous.

http://www.whathifi.com/Review/Wharfedale-Diamond-90/


High end audiophile speakers they are not, but then nor is anything under £2,000, and certainly nothing as small as the Diamonds. But plastic boom boxes they are not either. They are well designed, well built small speakers for use in space restricted budget systems, and when set against the standard of other speakers that you can buy for £100 (they are on offer in Bobs link) they come out very well.

In all honesty, most £300 speakers are so flawed that they're almost unlistenable to and the fact that they make an attempt to be proper hi-fi actually makes them worse by just drawing attention to their limitations.

The awfulness of most mid-range speakers is the reason I went down the DIY route, (as mid-range is all I could afford), until eventually Wife acceptance factors forced me in to getting hold of an end of line deal on a pair of AE floorstanders. Despite the fact that they retailed for £750 a pair, (which I certainly didn't pay for them), even they took me a long time to get used to their flaws, and to an extent I still haven't.

Quote from george_tsiros :maybe i'm behind the times, but 50% of the budget on speakers (2) 20% on source (1) 20% on amp (1) 9% on cables etc, 1% on chocolate (2).

every system sounds better when you're eating chocolate.

Wow !!.. I haven't seen that split recommended since before Linn proved the importance of source quality !! (no I'm not that old).

Ok maybe in the day of CD front ends things have shifted around a bit and whilst I would generaly agree that good speakers are expensive, (as you state a completely different kind of engineering involved), I'm not sure that balance is right for all levels of equipment.

I get where Bob is comming from, at the level being discussed here people should really only be looking at getting the fundamental balance right. Niceties of dynamics etc are all way out of this budgets price range. I would also go for a reasonable amp and "essentially" neutral speakers (which the diamonds have always been in the past). At this level it's not really about getting speakers that can reveal the differences between amps its just about getting speakers and amp that aren't massively flawed.

Quote from Syfoon :You could run monitors through an amp, but it'd be a waste of high-end speakers.

They're self-powered for a reason, so they deliver a nice sound all the way through the EQ range. Normal amps often distort somewhere on the EQ, producing more bass or more high-end. Monitors are built not to do that. Using an amp will make all the hard work the R&D guys put in useless

Sorry but no sub £500 "active" monitor is going to be neutral at all spl levels. An amp is an amp, it's not relevant where it sits physically with regard to it's quality. There are a lot of audio quality issues relating to physically placing amps inside speaker cabinets but there are of course some audio quality benefits, as with everything there are pros and cons. But ultimately the pro of active speaker amplification is far outweighed by the actual quality of the amplifier, and the amplifier in any £250 set of active speakers is going to be a long long way from perfect.

Quote :
Same with cheap speakers. They don't kick out a flat sound. Hi-fi speakers are the same, they're usually overly bassy. Much cheaper to build them flawed.

And those Alesis are not going to "kick out" anywhere near a flat sound either at that price point. If by "Hi-Fi" speakers you mean your average £200 JVC etc that most people would have in their homes then maybe they are a bit bass heavy. But many are the complete opposite, you simply can't generalise like that. True audiophile speakers try and balance absolute neutrality with good dynamics. This is always a compromise as the laws of physics dictate that the higher the senitivity of a drive unit is the narrower, (and often more uneven), it's frequency response is.

Studio montors aren't actually built to be "accurate" despite what all the speil you might read about them might say. They are designed to be "revealing" to allow the engineers to be able to hear what is going on in the mix and to be able to play very loud. To this end they are nearly all, (bar the extreme top end custom built designs), bright in the midrange.

Final note, a speakers final tonal balance is heavily dependant on the environment of it's use. Speakers interact with their surroundings. A speaker that may be bass heavy in one room will be neutral or even bass light in another and vice verse.

Oh and a final final note.. small speakers, (by which I mean anything that isn't at least a meter high floorstander), are incapable of being "accurate" , (even in terms of frequency response), over the the entire audiable spectrum. Very few speakers on the market today have any significant response as low as ,(let alone below), 40hz. The majority can't even produce a Bass guitars E string fundamental at the correct level let alone its sub harmonics.

Quote from Syfoon :Depends on what you're going to be using them for, how loud you want them to go, and more importantly, how crisp you want the sound to be.

I've got a set of Alesis Active mk1's, and they're stunning. Amazing sound quality (best I've ever owned), but they aren't overly loud, so you can jack them up and not get in too much trouble

How what?? I bet you just love your peizo tweeters huh?

The term "crisp" has no meaning let alone place in real Hi-Fi.

Ahh Alesis.. that'll explain it then.. studio monitor "accuracy"

Quote from BlueFlame :Yea, Collard is a wrecker, he obviously knew his race was over, final race of the day and just wanted to take someone out. He clearly wasn't on his brakes after he skidded across the grass because his wheels weren't locked, they were spinning freely. I voted no because I don't think Collard gave Nash any room, he tried to shut the door but obviously misjudged where Nash was and ended up getting shunted. He clearly should of been on the brakes tho when he was coming back across the track and for that clear-cut sign of an intentional wreck, I think (even if Nash rammed him) that Nash shouldn't be DQ'd.


EDIT : And about Rob Collard being injured, he's a liar, either way, Nash and Collards contact was not the cause of Rob's "injuries". The cause of his "hospitalization" was hitting Jelley and Rob could of avoided hitting Jelley by being on the brakes instead of letting it coast back on track like a complete idiot. So what if Nash gave a couple of nudges, Collard deserves it cos he's a grade A wrecker. Sure, it's not good racecraft, but when you nudge a guy off when it's his own fault for shutting the door and he intentionally wrecks other people to try and get the race red flagged then you aren't gonna feel too happy about people investigating your taps on a guys back end (yes the pun was intended) before the incident happened. I know I don't drive like that on LFS, if you nudged someone to gain an advantage then it's poor racecraft and in a league you'd surely be penalized but generally leagues are run by people who are racing in the series. Most popular motor-racing is governed by people who AREN'T racing in the series, therefore their judgement is somewhat kaleidoscopic.

Only thing I'll say to that tirade is...

Ever tried braking on a downhill bank of grass after loosing control at over 100mph??

No didn't think so.

Where he ended up had very little to do with what he did with any of the controls of the car. Once shunted and on the grass he was in the lap of the gods as to where he stopped.

Quote from trebor901 :I think one small nudge is acceptable but no a proper whack, and as you say if the cars scrape as they go by each other and it doesnt effect anyone then that is alright.

At the speeds they are driving at and the fact that the cars are close to the limit most of the time there is no such thing as "one small nudge", and all the racers in that series know it. To my mind Nash was clearly continously nudging in order to unbalance the car in front. That's not sporting behaviour IMO. Taken "in context" of what else was happening, (which the stewards most likely did), I think a DQ was fairer than any fine.
The only thing that you can do to prevent unsporting behaviour is to directly penalise it where it really counts and that is the championship itself. Fines don't change driver behavior. If they're still allowed to win the championship in the end, they'll see it as an acceptable cost.

Quote from amp88 :Takes a lot of strength and energy to use the brakes. You can't have power brakes in F1 and we've heard so many times that the drivers are applying around 100kg of pedal pressure at the hard braking areas lap after lap after lap. That puts a lot of stress through the leg and also through the hips as the body tends to twist. Think how hard it would be to do several hundred 100kg leg presses in a 60+ degree Celsius environment whilst being subjected to large G forces and having to concentrate on trying to extract 100% from your car.

Nice analogy, shame it's not how you apply pressure to a brake pedal. Braking is done almost exclusively by the calf muscle, and counter intuitive as it may seem the calves are actually capable of exerting a hell of a lot more force than the quads in unseasoned weight trainers and do so repeatedly. I'm not saying that 100kg brake pedal force is anything to be sniffed at, (given the environment), but as a pure force it's not that much for a calf. Most people can easily do one legged calf raises of their own body weight. Given the average male weighs 70kg+, it puts a 100kg pedal force somewhat in to perspective. It's mostly down to endurance than actual real strength.

Plus, given their relatively slight builds, I'd be willing to put money on most F1 drivers not being able to rep 100KG squats !! (at least proper below parallel ones).

I'm not for a second trying to say that F1 drivers don't need a good level of fitness, (certainly far better than an average member of the public has). But as with everything, fitness etc is relative and F1 drivers don't have the cardio-vascular fitness of distance runners nor the strength of wrestlers, weight lifters etc and they certainly don't have a combination of both !! Just trying to put a little perspective in to the discussion.

Quote from tristancliffe :1. Then drop the silly 'use both compounds' rule.
2. What has Indy '05 got to do with this? Again, you show how little you recall of the event.
3. Exactly. At the moment (and for quite some time) overtaking has been difficult because of the aero. However, rather than try to overtake against the odds, they are happy to sit and wait for their stops. After all the pitstops are done we generally see a bit more overtaking as the drivers can no longer rely on waiting (though of course this isn't always the case, as they may 'settle for position').

Remove mandatory pitstops, provide a tyre that can cope with a race distance (perfectly possible - humans can make tyres that last for hundreds of thousands of miles, so why should 200 miles be difficult), and at least get the drivers in the frame of mind that encourages overtaking.

Amen to that !!

Let the cars go through the transition of being over heavy on good rubber to light on cooked rubber and everything in between and we'll see who the true drivers, (and chasis dev engineers), really are !!

To drive a performance car through a wide range of handling responses such as would be the case in a non-stop race takes the highest level of driving skill. That's always been a part of reason why there have always been drivers that are "qualy" specialists that never deliver the goods over race distance. Take away the pit stops and you'll be moving even further away from the situation of having a series of short sprints with an "ideal" car, which in all honesty doesn't really prove much with regards to driving ability IMO.

Quote from CrAZySkyPimp :I bet you think riding motocross is just "sit and turn the throttle" right?

The two are not comparible, and you know it.

In what way does an F1 driver make use of any of the muscles in his body ?? With the exception of resistance to G-Forces they don't. F1 drivers require almost exclusively isometric strength in some parts of their bodies they don't under go even partial ROM for there to be any dynamic element to their strength requirements.

As for their elevated heart and respiratory rates during a race, they are purely down to adrenaline being dumped in to the bloodstream as a result of generalised stress levels, very little to do with cardio vascular exersion.
