In a banked turn, the bank angle allows the normal force to provide a component of the centripetal force, reducing the reliance on friction. The relationship can be expressed as the inequality: $\mu mg > \frac{mv^2}{r}$, where $\mu$ is the coefficient of friction, $m$ is the mass of the vehicle, $g$ is the acceleration due to gravity, $v$ is the speed, and $r$ is the radius of the turn.

The maximum cornering speed, given by the inequality $v < r \mu g$, represents the fastest speed at which a vehicle can safely negotiate a banked turn without relying solely on friction for centripetal force.

A surface is considered flat in the context of a banked turn when the bank angle is zero, resulting in the normal force being vertically upward and the only force keeping the vehicle turning being friction or traction.

Friction provides the centripetal force required to keep the vehicle on its path in a banked turn. It must be large enough to satisfy the inequality $\mu mg > \frac{mv^2}{r}$, where $\mu$ is the coefficient of friction, $m$ is the mass of the vehicle, $g$ is the acceleration due to gravity, $v$ is the speed, and $r$ is the radius of the turn.

The bank angle allows the normal force to contribute to the centripetal force, reducing the force required to turn the vehicle. This force is given by the expression $\frac{mv^2}{r}$, where $m$ is the mass of the vehicle, $v$ is the speed, and $r$ is the radius of the turn.
