1.)

2.) 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 4, 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
