Explanation: The perpendicular which is erected while setting curve by bisection of arcs, is equal to versed sine of the curve which makes it equal to \( R – (R^2 – (\frac{l}{2})^2)^{1/2}\).

10.26*(1- cos (10˚24ꞌ/2)) = 0.042 m.

Explanation: Since the bisection of each chord is involved in this method, this may have an advantage over the remaining methods. The bisection can provide accuracy by involving each step closely.

34.76*(1-cos (14˚76ꞌ/4)) = 0.28 m.

Explanation: Versine is the indication of the inversion of sine i.e., sin-1. Among the following, 1-cos θ represents the versine value. This is done for improving technical knowledge.

Explanation: Bisection is the main process involved in the successive bisection of the chords method. For the erection of perpendicular offsets it is must for developing the bisection process, as it provides the points necessary for perpendicular offsets.

Explanation: The successive bisection of chords involve in determining the offsets points and also in erecting the perpendicular offsets. The main advantage of this method involves generation of more amount of points by which this process can be continued.

\(34.98 – (34.98^2- (\frac{12.65}{2})^2)^{1/2} = 0.57m.\)

Explanation: The simple curve setting methods involve certain category off which, the successive bisection of chords is one of them. It is a tedious procedure because it involves the bisection of each chord.
