Hi all,
Hope u fellows luv to wath F-1 racing.I got mail regarding few facts about this sport.know these...
01. An F1 car is made up of 80,000 components, if it were assembled
99.9% correctly.
02. Formula 1 cars have over a kilometer 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....
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
traveling up and down 300 times a second!!)
09. The brake discs in an F1 car have an operating temperature of
approx. 1000 degrees 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.
F1 cars 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 traveling 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.
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 at 100C
remember) At top speed, F1 tyres rotate 50 times a second.
c ya later...
