Centripetal Force: Why Static Friction is Used in Bank Curve Problems

[oreo]

Why do we use coefficient of static friction instead of coefficient of kinetic friction in bank curve problems

When the wheels start sliding sideways things start getting complicated, and very exciting. When the part of the wheel in contact with the paved surface/track is not moving relative to the track (static case), things are under control.
