Question 1
A highway curve measures a radius of 200 m. Calculate the super-elevation needed for a vehicle traveling at 90 km/h considering lateral friction.
💡 Hint: Use the formula e = (0.75v)^2 / (gR) to simplify.
Question 2
You have a curved road where a truck with a high center of gravity must navigate. Discuss whether the rotation about the center line or inner edge would provide better stability. Justify your response with principles of super-elevation.
💡 Hint: Evaluate how each method affects vehicle dynamics.
