A transition curve of the cubic parabola type is to be set out from a straight center-line. It must pass through a point which is 6 m away from the straight, measured at right-angles from a point on the straight produced, 60-m from the start of the curve. a) Tabulate the data for setting out a 120-m length of curve at 15-m intervals. b) Calculate the rate of change of radial acceleration for a speed of 50km/h [25 Marks] [25 Marks] NB: the 120m is just part of the total transition curve, therefore, the full-length L is unknown.
