Challenge Problems
Push your limits with challenges.
Question 1
A highway curve has a radius of 80 meters. What is the maximum speed a vehicle can safely travel without skidding if the coefficient of friction is 0.15?
💡 Hint: Use the friction and gravity to calculate the maximum allowable speed.
Question 2
Design a road curve for a speed of 60 km/h with a radius of 50 m. Calculate the required super-elevation.
💡 Hint: Ensure to convert units properly and remember to account for the friction.
