A simple curve having a degree of curve equal to 5° is connected by two tangents having an azimuth of 230° and 280° respectively. It is required to replace this curve by introducing a transition curve 80 meters long at each end of a new central curve which is to be shifted at its midpoint away from the intersection of the tangents. (a)Determine the radius of the new central curve if the center of the old curve is retained. (b)Determine the distance which the new curve is shifted away from the intersection of the tangents. (c)Compute the length of throw.
