Question
The second curve in a compound curve is connected to another simple
curve in opposite direction. The common tangent of the compound
curve makes an angle of 45° and 60° with the first and second tangent
of the simple curves. The long chord of the compound curve is 458.025
m. The angle of convergence between the second tangent of the
compound curve and the tangent of the reverse curve is 15°. The radii
of the first, second and third curve are 190.986 m, 381.97 m, and
159.155 m respectively. Determine the following:
a. The long chord of the first simple curve.
b. The long chord of the second simple curve.
c. The angle (in nearest minute) which the long chord of the
compound curve makes with its first tangent.
d. The angle (in nearest minute) which the long chord of the
compound curve makes with its second tangent.
If the stationing of the beginning of the compound curve is at
10+520 m, find:
e. The stationing of the point of compound curve.
f. The stationing of the point of reverse curve.
g. The stationing of the end of the reverse curve.
