Engineering Mechanics - Dynamics Chapter 12 Problem 12–117 Cars move around the “traffic circle” which is in the shape of an ellipse. If the speed limit is posted at v , determine the maximum acceleration experienced by the passengers. Given: v 60 km hr = a 60 m = b 40 m = Solution: Maximum acceleration occurs where the radius of curvature is the smallest. In this case that happens when y = 0. xy () a 1 y b 2 = x' y y d d = x'' y y x' y
