2 a) Give the steps involved in the setting out of a simple curve by successive (5)

bisection of arcs.

b) Two tangents intersect at chainage of 1200m, the deflection angle being 425. (10)
Compute all the data necessary to set out a curve of radius 300m by Rankine’s
method. The peg interval is 30m.

3 ஐ Elaborate the steps in the computation of Gales traverse table. (8)

b) The chainage of intersection of two straight lines having deflection angle 55° 18 (7)
1000m. If the radius of the curve is 400 m, calculate the five elements of the
simple curve and the chainages of point of curve and point of tangency.
