Determine the elevation of an unknown point X which lies between two known points A and B along an alignment tangency. The profile of tangency AB is also a tangent.
Known values:
Solution: Elevation of point X, HX.
The road has a constant grade S along the examined section, which equals to tangent angle α, formed by the tangent AB and the horizontal plane.
Grade S calculation:
