Understanding the Sport - F1
Aerodynamics
A modern Formula One car has almost as much in common with a jet fighter as it does with an ordinary road car. Aerodynamics have become key to success in the sport and teams spend tens of millions of dollars on research and development in the field each year.
Brakes
When it comes to the business of slowing down, Formula One cars are surprisingly closely related to their road-going cousins. Indeed as ABS anti-skid systems have been banned from Formula One racing, most modern road cars can lay claim to having considerably cleverer retardation.
Cockpit / safety
At the heart of the modern Formula One car lies the immensely strong 'monocoque' structure, often referred to as the 'tub'. This incorporates the cockpit and the driver's 'survival cell', but also forms the principal component of the car's chassis, with the engine and the front.
Cornering
Cornering is vital to the business of racing cars, and Formula One is no exception. On straights the battle tends to be determined by the power of engine and brakes, but come the corners and the driver's skill becomes more immediately apparent.
Driver fitness
Formula One drivers are some of the most highly conditioned athletes on earth, their bodies specifically adapted to the very exacting requirements of top-flight single-seater motor racing.
Drivers' clothing
Formula One helmets are designed around the clear need to protect drivers' heads from the risk of major impacts. But the rest of his clothing has an equally serious purpose: offering the best possible defence against the risks of fire.
Engine / gearbox
The engine and transmission of a modern Formula One car are some of the most highly stressed pieces of machinery on the planet, and the competition to have the most power on the grid is still intense.
Flags
Marshals at various points around the circuit are issued with a number of standard flags, all used to communicate vital messages to the drivers as they race around the track. A special display in each driver’s cockpit - known as a GPS marshalling system also lights up when the flags are on.
Fuel
Surprising but true, despite the vast amounts of technical effort spent developing a Formula One car, the fuel it runs on is surprisingly close to the composition of ordinary, commercially available petrol.
HANS
HANS stands for the Head and Neck Support system, an innovative safety device that has been seen in other codes of motorsport for years, but which became mandatory in Formula One for the first time in 2003. Its purpose is simple: to massively reduce the loadings caused to a driver.
Helmets
One of the most important safety devices in Formula One racing is the driver's helmet. Although its fundamental shape may look very similar to those worn by drivers in the 1980s and even the 1970s, the underlying design and construction technology has changed radically over the years.
Overtaking
As only one driver can ever sit on pole position for a race, and the entire grid wants to finish on the top step of the podium, overtaking is of vital importance to the business of racing. Simplified to its most basic form overtaking is nothing more than gaining track position.

Some Interesting Facts - Formula1 Racing
01. An F1 car is made up of 80,000 components, if it were assembled 99.9% correctly, it would still start the race with 80 things wrong!
02. Formula 1 cars have over a kilometre of cable, linked to about 100 sensors and actuators which monitor and control many parts of the car.
03. An F1 car can go from 0 to 160 kph AND back to 0 in FOUR seconds !!!!!!!
04. F1 car engines last only for about 2 hours of racing mostly before blowing up on the other hand we expect our engines to last us for a decent 20yrs on an average and they quite faithfully DO....thats the extent to which the engines r pushed to perform...
05. When an F1 driver hits the brakes on his car he experiences retardation or deceleration comparable to a regular car driving through a BRICK wall at 300kmph !!!
06. An average F1 driver looses about 4kgs of weight after just one race due to the prolonged exposure to high G forces and temperatures for little over an hour (Yeah thats right!!!)
07. At 550kg a F1 car is less than half the weight of a Mini.
08. In an F1 car the engine typically revs upto 18000 rpm,(the piston travelling up and down 300 times a second!!) wheres cars like the palio, maruti 800,indica rev only upto 6000 rpm at max. Thats 3 times slower.
09. The brake discs in an F1 car have an operating temperature of approx 1000 degees Centigrade and they attain that temp while braking before almost every turn...that is why they r not made of steel but of carbon fibre which is much more harder and resistant to wear
and tear and most of all has a higher melting point.
10. If a water hose were to blow off, the complete cooling system would empty in just over a second.
11. Gear cogs or ratios are used only for one race, and are replaced regularly to prevent failure, as they are subjected to very high degrees of stress.
12. The fit in the cockpit is so tight that the steering wheel must be removed for the driver to get in or out of the car. A small latch behind the wheel releases it from the column. Levers or paddles for changing gear are located on the back of the wheel. So no gearstick! The clutch levers are also on the steering wheel, located below the gear paddles.
13. To give you an idea of just how important aerodynamic design and added downforce can be, small planes can take off at slower speeds than F1 cars travel on the track.
14. Without aerodynamic downforce, high-performance racing cars have sufficient power to produce wheel spin and loss of control at 160 kph. They usually race at over 300 kph.
15. The amount of aerodynamic downforce produced by the front and rear wings and the car underbody is amazing. Once the car is travelling over 160 kph, an F1 car can generate enough downforce to equal it's own weight. That means it could actually hold itself to the CEILING of a tunnel and drive UPSIDE down!
16. In a street course race like the monaco grand prix, the downforce provides enough suction to lift manhole covers. Before the race all of the manhole covers on the streets have to be welded down to prevent this from happening!
17. The refuelers used in F1 can supply 12 litres of fuel per second. This means it would take just 4 seconds to fill the tank of an average 50 litre family car.They use the same refueling rigs used on US military helicopters today.
18. TOP F1 pit crews can refuel and change tyres in around 3 seconds. & 8 sec to read above point.
19. Race car tyres don't have air in them like normal car tyres. Most racing tyres have nitrogen in the tyres because nitrogen has a more consistent pressure compared to normal air. Air typically contains varying amounts of water vapour in it, which affects its expansion and
contraction as a function of temperature, making the tyre pressure unpredictable.
20. During the race the tyres lose weight! Each tyre loses about 0.5 kg in weight due to wear.
21. Normal tyres last 60 000 - 100 000 km. Racing tyres are designed to last 90 - 120 km (That's Khandala and back).
22. A dry-weather F1 tyre reaches peak operating performance (best grip) when tread temperature is between 900C and 1200C.(Water boils boils at 100C remember) At top speed, F1 tyres rotate 50 times a second.
So Formula Driving is not piece of cake, DEAR!!! No Wonder, thats why Michael Schumacher is the world richest Sports Person!!!!

4.) If any service provider wants to pay for this kind of activities they might get a small space for donation in their website.
Note: If you are going to make a donation online, see if that the website is a legitimate one. Also you might have noted and experienced as well that you would get money if you forward this mail to 100 people etc and so on. So inorder to do this the SPAMMERS they use the reputed companies name like Microsoft Corporation, AOL and so on. Also sometimes it comes with some attachments which might be a virus file.
Though there are Spam Blockers installed in the system, people anyway manage to get these kinds of email and forward it to their friends in their contact list. So it is in the hands of us, not to encourage these kinds of emails.

WIFE VS. HUSBAND | Jokes | Funny Stories | Huband & Wife Jokes | The Silent Treatment
WIFE VS. HUSBAND
A couple drove down a country road for several miles, not saying a word. An earlier discussion had led to an argument and neither of them wanted to concede their position. As they passed a barnyard of mules, goats, and pigs, the husband asked sarcastically, "Relatives of yours?"
"Yep ," the wife replied, "In-laws."
WORDS
A husband read an article to his wife about how many words women use a day... 30,000 to a man's 15,000. The wife replied, "The reason has to be because we have to repeat everything to men...The husband then turned to his wife and asked, " What?"
CREATION
A man said to his wife one day, "I don't know how you can be so stupid and so beautiful all at the same time.
" The wife responded, "Allow me to explain. God made me beautiful so you would be attracted to me;
God made me stupid so I would be attracted to you!
WHO DOES WHAT
A man and his wife were having an argument about who should brew the coffee each morning.
The wife said, "You should do it, because you get up first, and then we don't have to wait as long to get our coffee." The husband said, " You are in charge of cooking around here and you should do it, because that is your job, and I can just wait for my coffee." Wife replies, "No, you should do it, and besides, it is in the Bible that the man should do the coffee." Husband replies, "I can't believe that, show me." So she fetched the Bible, and opened the New Testament and showed him at the top of several pages, That it indeed says........ .. "HEBREWS"
The Silent Treatment
A man and his wife were having some problems at home and were givingeach other the silent treatment. Suddenly, the man realized that the next day, he would need his wife to wake him at 5:00 AM for an early morning business flight.

The next morning, the man woke up, only to discover it was 9:00 AM and he had missed his flight. Furious , he was about to go and see why his wife hadn't wakened him, when he noticed a piece of paper by the bed. The paper said, "It is 5:00 AM, Wake up."
