Two straight lines intersect at an angle of 60°. The radius of a curve joining the two straight lines is 600 m. The length of long chord and mid-ordinates in metres of the curve are
-
- 8.4, 600.0
- 600.0, 80.4
- 600.0, 39.89
- 40, 89, 300
- 8.4, 600.0
Correct Option: B
| Length of long chord = 2R sin | = 2 × 600 × sin 50 = 600 m | |
| 2 |
| Length of mid ordinate = L |  | 1 - cos |  | ||
| 2 |
= 600 (1 – cos 30°) = 80.38 m
