Highway curves banked and unbanked
WebHighway curves are marked with a suggested speed. If this speed is based on what would be safe in wet weather, estimate the radius of curvature for an unbanked curve marked 80 km/hkm/h . Use Table 4-2 in the textbook (coefficients of friction). Express your answer to one significant figure and include the appropriate units. Expert Solution WebQuestion: A flat (unbanked) curve on a highway has a radius of 220 m. A car successfully rounds the curve at a speed of 35 m/s but is on the verge of skidding out.
