The back tangent AV of a simple curve has an azimuth of 252° while that of its forward tangent VB has an azimuth of 300°. The degree of the simple curve is 4º, arc basis. It is desired to replace the simple curve with another curve having 100 m spiral at its end without changing the points of tangency. Solve for the following: a. Radius of the central simple curve b. Super elevation of the spiral easement curve C. Distance along the tangent at the third quarter point of the spiral
