Read on for must-know info for NASCAR fans
Last week, I offered simple descriptions of some words and phrases often used by NASCAR commentators.
Straight from my NASCAR "Page A Day Calendar, there are plenty more for me to share.
So, without further delay, here are a few must-know expressions for the knowledgeable NASCAR fan:
n A yellow strip across the rear of a race car means it's a rookie driver.
• Provided qualifying is not cancelled, 38 cars are normally set in the starting grid by qualifying speed.
• Stagger is the difference in size between the tires on the left and right sides of a car.
• The three-year rule means you cannot use a body of a car that is more than 3 years old.
• "Camshaft" -- A rotating shaft within the engine that opens and closes the intake and exhaust valves.
• "Drag" -- The resistance a car experiences when passing through air at high speeds, a resisting force exerted on a car parallel to its airstream and opposite in direction to its motion.
• "Wheelbase" -- The distance between the axles on the same side of the car.
• "Deck lid" -- The rear trunk lid of a race car. It opens like the trunk lid of a passenger car and allows access to the fuel cell.

I don't know if any of this has been helpful to you, but I sure feel smarter.
