## Homework Statement

A civil engineer is asked to design a curved

section of roadway that meets the following

conditions:

With ice on the road, when the coefficient of

static friction between the road and rubber is

0.1, a car at rest must not slide into the ditch

and a car traveling less than 80 km/h must

not skid to the outside of the curve. The road is banked at an angle of 5.71059 degrees

What is the minimum radius of curvature of

the curve?

## Homework Equations

I thought the equation to use was v^2= gr tan (theta)
