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.
