Question

Curves on some test tracks and race courses, such as the Daytona International Speedway in Florida, are very steeply banked.

Answer 1

Answer #1

Consider banking angle of the road. On the inclinde plane the normal force is N.

The component of normal force along horizontal is N sino = centripetal force

N sini = mut

Ncost = mg

The ratio of abive equations is N sino Ncost mv2/R mg

TanᎾ =

e = Tan-144

O=Tan- 56.4.c9.8

$\Theta =$ 75.40

The Texas Motor Speedway is an oval racing track with curves of radius 229 m that are banked at an angle of 24.0°. The size of the track allows for race cars to achieve speeds in excess of 400 km/h. An unintended consequence of the banked curves and high speeds is that race car drivers experience excessive G forces, especially in the "vertical" direction (with respect to their body position), causing dizziness and loss of consciousness.
