PROBLEM 1 A SIMPLE CURVE HAVING A CENTRAL ANGLE OF 40 DEGREES AND EXTERNAL DISTANCE OF 20M CONNECTS TWO TANGENTS. IT IS TO BE REPLACED BY ANOTHER CURVE HAVING 70M SPIRALS AT ITS ENDS SUCH THAT THE TANGENTS AND POINT OF TANGENCY SHALL BE THE SAME. a.) DETERMINE THE RADIUS OF THE NEW CIRCULAR CURVE b.) IF THE ROAD WIDTH IS 8M, COMPUTE THE SUPER-ELEVATION 20M AWAY FROM T.S. c.) COMPUTE THE OFFSET DISTANCE FROM TANGENT AT S.C.
