From a known point V (vertex), the tangent lines of a compound curve are drawn - having azimuths 300° (forward tangent) and bearing N 04° E (back tangent), respectively. A common tangent line CD intersects the two tangent lines at bearing S 34° E. Stationing of the vertex of the compound curve is 16 + 464.35 and the distance from point D to the vertex of the compound curve is 137.6 m. If the external distance of the curve passing through the PC is 1.42 times the external distance of the simple curve that passes through the PT, solve for the following. a. Radius of the curve that passes through the PC
From a known point V (vertex), the tangent lines of a compound curve are drawn -
having azimuths 300° (forward tangent) and bearing N 04° E (back tangent),
respectively. A common tangent line CD intersects the two tangent lines at bearing S
34° E. Stationing of the vertex of the compound curve is 16 + 464.35 and the distance
from point D to the vertex of the compound curve is 137.6 m. If the external distance of
the curve passing through the PC is 1.42 times the external distance of the simple curve
that passes through the PT, solve for the following.
a. Radius of the curve that passes through the PC
b. Radius of the curve that passes through the PT
c. Stationing of the PT
