| Radius of Curve |
In this convention, a curve is designated by its radius. The sharpness of the curve depends upon its radius. A sharp curve has a small radius. On the other hand, a flat curve has a large radius. Moreover, from (Equation 37.9), it can be found that the degree of curve is inversely proportional to the radius of curve. Thus, a sharp curve has a large degree of curve, whereas a flat curve has a small degree of curve. |
