Challenge Problems
Push your limits with advanced challenges
A vehicle is moving at 25 m/s through a curve with a radius of 50 meters. Calculate the required super-elevation if friction coefficient is 0.15.
💡 Hint: Convert speed into appropriate units and substitute into the equations.
Analyze how the curve design changes if the terrain shifts from flat to mountainous. What implications does this have on super-elevation?
💡 Hint: Consider friction and vehicle dynamics when recalculating super-elevation for safety.
