Curva Orizzontale: Risoluzione di Problemi

A horizontal curve has a radius of 400 meters, and the angle of intersection is 30 degrees, the station of point of curvature is 0 + 150 meters.

The objective is to determine the stations of the point of intersection, point of tangency, and midpoint of the curve, as well as to calculate the length of the long chord.

To identify the stations, the tangent distance and length of the curve are first calculated using the radius, and intersection angle of the curve.

The station of the point of intersection is given by adding the length of the tangent to the station at the point of curvature.

The station of the point of tangency is calculated by adding the length of the curve to the station at the point of curvature.

Lastly, the station of the midpoint is found by adding half the curve's length to the station of the point of curvature. 

Then, the length of the long chord is obtained by the corresponding expression.
