Problem Statement: ME Board October 1997
A concrete hi-way curve with a radius of 500 ft is banked to give lateral pressure equivalent to f = 0.15. For what coefficient of friction will skidding impend for a speed of 60 mph?
- A. µ > 0.360
- B. µ < 0.310
- C. µ > 0.310
- D. µ < 0.360
The coefficient of friction that will skidding impend for a speed of 60 mph is µ < 0.310.
