1. The Degrees of Racing Created by Keith Johnson, Alan Riley, and Brandon Sasser

2. The History Of NASCAR • 1936 Daytona Begins the Dream • The Sacrifice of War • 1948 The Birth of National Association for Stock Car Auto Racing (NASCAR) • Bill France, Founder of NASCAR and International Speedway Corporation (ISC) • 1971 Winston Cup Series Begins • 2004 Nextel Cup Series Begins

3. The Southern Sport Goes National • NASCAR becomes #1 spectator sport in 2000. • Eighty million television viewers in 2000 • 3 divisions of NASCAR • Winston Cup Series • Busch Series • Craftsman Truck Series

4. Banking On The Turn

5. Design Speed Equation

6. Equation of Maximum Velocity • (Vmax)2 = [(sin + scos) / (cos - ssin)]gr •  is equal to the degree of banking of the particular turn • s is the coefficient of static friction between the track and the tires • g is acceleration due to gravity • r is the radius of the particular turn

7. Derivation of Maximum Velocity Equation

8. Darlington Raceway 1.366-Mile Egg-shaped Oval Backstretch Length: 1,229 Ft Width: 90 FtBanking: 2° Turns 3 & 4 Banking: 23° Width: 62 Ft Radius: 525 Ft Turns 1 & 2 Banking: 25° Width: 79 FtRadius: 600 Ft Frontstretch Length: 1,229 Ft Width: 90 FtBanking: 3° Qualifying Record: 173.797 mph
