just found this - Same guy and machine looks a lot more appropriate:

That's different though, isn't it? I mean when a jet turns, it has to roll onto it's side and then the pilot pulls up and there's your turn. So there's more g-forces pressing down on your head. F1 cars don't turn like that, they turn laterally.

just wasting his money on that thing,better out his money on right choice( i prefer to start a racing career with that money,rather to spent allover in a simulator that costs$$$$)

think about it now...i totally remember martin brundle saying
when f1 drivers accelerate it feels like their head is being lifted up too because of the force or something, then obviously the opposite effect when braking...head feels like its getting pushed down.
Im not sure why, but im going to read more into this after my exams unless someone can explain by then

I think he would have been reffering to the buffeting effect on your head. where your head gets forced backwards, or sometimes the air forcing itself at you can actually get under your crash helmet and feel like it's trying to lift off your head. Braking hard and quickly will also sometimes feel like your head is being forced down towards your chest. These things are due to weak neck muscles.

Even if you were to move up or down, it's very unlikely that the compression in your spine would be visual, it's probably more a visual illusion - moving in the seat maybe?? You can be strapped in as tight as possible and still findyourself moving. Steve Kane had that problem during his Mclaren Test for winning The Autosport driver of the year. He was constantly finding himself moving around in the car under braking, he said at one point he hit the brakes and went so low in the car he couldn't see. I think this is due to him having a rubbish rushed seat fitting... he said they had 3 or 4 attempts at getting the seat right....

Oh of course but the forces felt are still the same.

A - G on your head of lets say -3g would still mean the forces on your neck muscles would be 3g. So either way acceleration, braking, or turning your neck is still going to have to support.

There has to be someone here who watched ALMS races on speed where they have shown it? Youtube isnt playing nice atm.

Yeah if anyone went karting when little and wore a slightly too big helmet you would have noticed it trying to lift off.

I see, but would both forces have the same effect of pushing you down? Ie, would the force of lateral turning push you down into the car the same way as the force of turning a jet, such that the force is coming down mostly vertically onto your head? Is it not more likely that in a car you would be pushed back, like when a plane is taking off, rather than pushed down, as when a plane is turning? I don't actually know, maybe you know more than I do on the subject

By the way, isn't it wonderful the way a simple thread can turn into a barnstorming scientific discussion

lol yeah it is haha. It may different driving an F1 car, due to the obvious difference in speeds and loads. At brands in particular, go through Paddock hill bend and just as you get to the bottom of the dip (before run to druids) the car can compress a lot there and it takes you with it. Feels like it's gonna suck you through the bottom of the car - especially if you havn't done your belts up very tight :S

Same feeling I guess at Eau Rouge.

I'm not going to join in on the finer aspects of the physical discussion, but Brundle does often refer to a drivers head "going down" under breaking.

It's probably not the best choice of words on his part, although lets face it, what words are appropriate?

I think it's either the drivers head going forwards and giving the illusion that it goes down because of the tilt. The head is going to move around a fair bit because of the forces involved in braking.

It's that or the driver sliding forwards in his seat a little bit, but that wouldn't make a great deal of sense because if there's one thing you don't want to be doing in a racing car is sliding around in your seat, it's bad enough in a go-kart.

the drivers head goes down because he is strapped in so tightly his neck acts as a pivot point

The Lopper is completely correct. a driver only really experiences lateral g's (along the y and z planes, assuming x is vertical), wheras a fighter pilot/tobaggonist is generally going vertically as well, hences the spine 'compressing'. Certain corners will produce this effect (Eau Rouge) but not many. Its basic physics people, Newtons laws!
