The point where the road alignment changes from a tangent to a curve is known as ___________.

Question

The analyses results of a water sample are given below. The non-carbonate hardness of the water (in mg/L) as CaCO\(_3\) is ......... (in integer).
Ca\(^{2+}\) = 150 mg/L as CaCO\(_3\)
Mg\(^{2+}\) = 40 mg/L as CaCO\(_3\)
Fe\(^{2+}\) = 10 mg/L as CaCO\(_3\)
Na\(^+\) = 50 mg/L as CaCO\(_3\)
K\(^+\) = 10 mg/L as CaCO\(_3\)
CO\(_3^{2-}\) = 120 mg/L as CaCO\(_3\)
HCO\(_3^{-}\) = 30 mg/L as CaCO\(_3\)
Cl\(^{-}\) = 50 mg/L as CaCO\(_3\); Other anions were not analysed.

Answer 1

In highway geometry, the transition from a straight path (tangent) to a circular curve is marked by specific points:

- Point of Intersection (PI): Where two tangents meet.
- Point of Curve (PC): Where the curve begins (tangent ends and curve starts).
- Point of Tangency (PT): Where the curve ends and tangent resumes.
Therefore, the point where the road alignment changes from a tangent to a curve is called the Point of Curve (PC).

Hence, the correct answer is (C).
