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 50 km/h. Use Table 4-2 (coefficients of friction). The radius of curvature for an unbanked curve marked with 50 km/h is estimated to be 28.1 m. See the step by step solution.
