Curvature unit in highway

WebBy substituting the expressions for centripetal acceleration a c ( a c = v 2 r; a c = r ω 2), we get two expressions for the centripetal force F c in terms of mass, velocity, angular velocity, and radius of curvature: F c = m v 2 r; F c = m r ω 2. 6.3. You may use whichever expression for centripetal force is more convenient. In mathematics, curvature is any of several strongly related concepts in geometry. Intuitively, the curvature is the amount by which a curve deviates from being a straight line, or a surface deviates from being a plane. For curves, the canonical example is that of a circle, which has a curvature equal to the reciprocal of its radius. Smaller circles bend more sharply, and hence have higher curvature. The curvatur…
