Challenge Problems
Push your limits with advanced challenges
Design a curve for a highway with a radius of 200 m and a speed limit of 100 km/h. Calculate superelevation and determine if it meets IRC guidelines.
💡 Hint: Check IRC limits after calculating the initial e.
For a heavy truck traveling at 40 km/h around a curve with a radius of 75 m, determine the necessary superelevation considering a high center of gravity that requires lower superelevation.
💡 Hint: Think about how vehicle dynamics change with speed and load.
