Exercise 37

Ex.37-1 A railway curve is to be tangential to each of the following lines :

Lines
W.C.B.
Length (m)
AB
0°
-
BC
90°
220
CD
140°
-

Determine the salient parameters of the simple circular curve.

Ex.37-2 Two straights AB and BC meet in an inaccessible point B and are to be connected by a simple curve of 600 m radius. Two points P and Q were selected on AB and BC respectively and the following data were obtained.

R APQ = 150°, R CQP = 160°, PQ = 150.0 m

Calculate the salient elements of the simple circular curve. Considering the chainage of point P to be 1000 m.
