Question

The angle at point of intersection of tangents indicate____________Which of the following curves helps in avoiding overturning of vehicles?The tangent distance of a long curve is given as____________

Options:

A . Radius of the arcSimple curve\(T = t_l – (t_s + t_l) \frac{sin⁡(Δ1)}{sin⁡Δ}\)

B . Angle of the arcTransition curve\(T = t_l + (t_s – t_l) \frac{sin⁡(Δ1)}{sin⁡Δ}\)

C . Curvature angleCompound curve\(T = t_l + (t_s + t_l) \frac{sin⁡(Δ1)}{sin⁡Δ}\)

D . Deflection angleReverse curve\(T = t_l + (t_s + t_l) \frac{sin⁡(Δ1)}{sin⁡Δ}\)

Answer: Option A
Answer: Deflection angleTransition curve\(T = t_l + (t_s + t_l) \frac{sin⁡(Δ1)}{sin⁡Δ}\)
