Question Your World - Some Hot Nascar Science

Have you ever thought about the numbers behind NASCAR?  We’re not talking about the number of your favorite driver; we’re talking about the amazing math and science behind these speedy racers.  For example those super powerful engines race around at incredible speeds. Some have even been known to go around 200 mph in a straightaway, thus producing a lot of engine heat.  Temperatures have been recorded at about 140 degrees INSIDE the car.  Compound that with the amazing about of heat from the friction of those wheels constantly rubbing against the track and we’re looking at some hot, hot, hot numbers!
 
So, 140 degrees inside the car and the heat of the track itself, we’re looking at some sweaty drivers!  In fact, some NASCAR drivers have been known to lose anywhere from 5 – 10 lbs simply from perspiration!
 
Those are some hot-hot rods!
