Q1:

Designation of a curve is made by :

A angle subtended by a chord of any length

B angle subtended by an arc of specified length

C radius of the curve

D curvature of the curve.

ANS:C - radius of the curve

The curve is designated by the radius of curve and angle subtended by the chord of a particular length (30m). Also called the degree of curve. Here only answer C is correct. So answer C is correct. According to me, the Design of the curve is done on the basis of Radius and Degree of the curve. Design of curve R = 1718 * V^2/D.
