A civil engineer is asked to design a curvedsection of roadway that meets the followingconditions:With ice on the road, when the coefficient ofstatic friction between the road and rubber is0.13, a car at rest must not slide into the ditchand a car traveling less than 70 km/h mustnot skid to the outside of the curve. The acceleration of gravity is 9.81 m/s2 .At what angle should the road be banked?Answer in units of degrees. Got this part already 7.4069What is the minimum radius of curvature ofthe curve?
