Which of the following is NOT an element of a horizontal curve?

  1. Long chord

  2. Length

  3. Radius

  4. Slope

The correct answer is: Slope

In the context of horizontal curves in surveying, elements such as the long chord, length, and radius are critical components that define the geometry of the curve. The long chord is a straight line that connects the endpoints of the curve, serving as a reference for understanding the overall span of the curve. The length refers to the distance along the curve itself from one point to another, which is essential for calculating the total distance traveled along the curve. The radius is the distance from the center of the curve to any point on the curve, which is fundamental for determining the sharpness or flatness of the curve. On the other hand, the slope is not an element of a horizontal curve. While slope may be relevant in vertical curves or in describing the grade of a road or pathway, it does not pertain to the specific geometric characteristics of a horizontal curve. Thus, in this context, slope is the correct choice as it is not a component of a horizontal curve's definition.
