TOPIC: FUNDAMENTALS OF SURVEYING

TAKENOTE: (IF POSSIBLE FIND THE FIRST VALUE OF L, USE RATIO AND PROPORTION USING SQUARED PROPERTY OF PARABOLA) I GIVE POSITIVE FEEDBACKS THANK YOU SO MUCH!!

A 3% ascending grade meets a descending grade at the vertex at sta. 20+100 and at elevation 120
m. The symmetrical parabolic curve connecting the tangents passes thru a point at sta. 20+130 with an
elevation of 117.525 m. If the highest point on the curve is located 84 m from PT, what is the length of the
curve connecting the tangents? Determine also the grade of the descending tangent and the elevation of the
highest point on the curve.
