A superspeedway in New Delhi has among the highest super-elevation rates of any track on the Indians Grand Prix circuit. The track requires drivers to negotiate turns with a radius of 335 m and 33° banking. Given this information, the coefficient of side friction required in order to allow a vehicle to travel at 320 km/h along the curve is:
-
- 1.761
- 0.176
- 0.253
- 2.530
Correct Option: A
| e + ƒ = | ||
| 9R |
V = 320 km/h
| = | = 88.89 m/s | |
| 3600 |
e = tanq = tan33°
| ∴ tan33 + ƒ = | = 2.404 | |
| 9.81 × 335 |
⇒ ƒ = 1.76
