Maybe a crap question but it's NOT Spam
 

If an F1 car brakes at a force of 5g does that mean an F1 car is self-braking. :confused:

Once the pedal has been pressed the pedal and foot would be pushed at 5g towards the front of the car pressing the pedal even more. If you include the drivers leg in that you would have (20kg x 5) 100kg pushing the pedal without the driver pressing down, seeing as they are in a more or less laying down position.

That's been bugging me for years......:cool:

It's a bit like when you brake with your left foot! Every time I've tried it I've almost nutted the windscreen.

Sooo true lol

Spud go and stand in the corner:) In those things your body is strapped back in the seat really tight and no matter how many G`s of braking force are applied you would always be able to pull your leg/foot off a brake pedal. If you were not strapped in it would be a different story, you might end up in a heap under the dash:eek:

Ahhhh but Bob your leg isn't restrained so you would have weight of leg x 5 pushing forward onto the break pedal so if you didn't have the strength to pull your leg back everything would lock up and you'd just go smashing into the barrier, it is rather a lot 20 times a lap for 2 hours.

Must be better than reading spam all day - bet Ash deletes this.......:)

F1 cars look like they are stopping quick on TV but when you see them live they are just incredible to watch under braking. I was in Montreal last year when JB came from the back to win sitting at the hairpin, they came down the straight at about 180 mph and slowed down for the bend in about 80 meters, just phenomenal.

Now, I know that F1 drivers are fit guys and perhaps only weigh 65-75kg? But that means that every time they stand up from sitting position, walk, sit back down, etc, etc their ankle, leg, etc is lifting (similar to pressing,...) 65-75kg... So pushing 100kg a few mm using the same muscles should be a piece of cake...?

And the 'loose' leg of course IS attached to the rest of their body which is held tightly in place. It's not like their thigh (the heavy bit of a leg) is lurching forward unchecked every time the brakes are applied...

''We press with up to nearly 200 kilos on the brake pedal,'' said Sébastien Buemi, a driver at the Toro Rosso team. ''We do not have assistance like power steering or assisted braking. But this is just as well because it allows us to feel it better. We control the braking much better. When we block the wheels, we are the ones who have to let go of the brake so that it is no longer blocked. A road car does that all by itself.''

Never realised there was so much pedal effort required :eek: to drive these cars and all the forces involved is quite amazing

The pit walk ex f1 driver martin brundel got back in a car in recent years for some press thingy and the thing that left him speechless was the braking. He said that it felt like his eyes were going to pop out of his head:eek: . Just had another thought on martin, did anyone see the pit walk when he stumbled across ozzy osbourne? He went up to ozzy and said something like what do you think af formula 1.,ozzy opened his mouth and out fell loads of utter garbled crap. Bearing in mind its live tv martin just looked at him and quick as you like "well I will go away and think of the question that goes with that answer" Classic.

Ok spud you can come out of the corner now and join the class:)

i used to love watching martin brundell forcing his way infront of that angry spanish tv woman, she always got arsy with him:eek: , im sure there was some chemistry there. Hardly watched it at all this season, iv been converted to rally, thats where the skill and bravery is:eek:

I think 200kg would be the force on the cylinder due to the leverage of the pedal.

I love Ozzy for the person he is and his music but that is a classic quote - only Martin could come up with that on the spot

I can't watch F1 any more I just find it all too boring, even a 20-30 stock car race is about my limit. I had 4 years of racing NASA Autograss/grasstrack 1600 stockhatch in an xr2 6 quick laps on 1/4 mile oval. In the summer the track would be as hard as tarmac and very dusty, if it rained it would be very slippery or even turn in to an inch of slop in same meeting. Winter races where alot of fun no need for left foot braking just turn in hard and get 90' of lift off over steer at 30-40mph.
£300-500 to build a car for a complete season of 14 meetings and maybe a new set of front rubber mid season. My first season cost me £2200 and that included the car,trailer,entry fees, fuel,lunch and a licence.

I've driven a single seater at PalmerSport, it was a 3ltr V6 Formula Jaguar and the force you have to apply to the pedal to brake is phenomenal.

It had a little light on the dash that came on when you applied enough pressure and believe me, it's a lot.

Even so, it'll be nothing to what they have to apply in an F1 car.

when the stop lever is that big compared to the go lever you know its gonna be quick
