Problem no. 3 A forward tangent having a slope of -4% intersects the back tangent having a slope +7% at point V at stations 6 + 300 having an elevation of 230m. It is required to connect the two tangents with an unsymmetrical parabolic curve that shall pass through point A on the curve having the elevation of 227.57m at station 6 + 270. The length of the curve on the side of the back tangent is 60m. A. Determine the length of the curve on the side of the forward tangent. B. Determine the stationing and elevation of the highest point on the curve.

Transcribed Image Text:Problem no. 3
A forward tangent having a slope of -4% intersects the back tangent having a
slope +7% at point V at stations 6 + 300 having an elevation of 230m. It is
required to connect the two tangents with an unsymmetrical parabolic curve
that shall pass through point A on the curve having the elevation of 227.57m at
station 6 + 270. The length of the curve on the side of the back tangent is 60m.
A. Determine the length of the curve on the side of the forward tangent.
B. Determine the stationing and elevation of the highest point on the
curve.
