Explanation:
Relation between length of a curve and angle is as follows.
l =
where, R = radius of curve
= angle in radians
Also, l = .......... (1)
If curve has a degree of curvature for standard length s, then
R = ........... (2)
Now, substitute the value of R from equation (2) into equation (1) as follows.
l =
If s = 30 m, then calculate the value of l as follows.
l =
=
= 452 m
thus, we can conclude that the length of the curve is 452 m.
