A curve has a radius of 500 m with a deflection angle of 30°. Calculate the Length of Curve and provide the Chainage if the PI is at 1000 m.
💡 Hint: Use the formulas we've discussed to guide your calculations.
If a radius of 300 m and a PI at 1200 m are given, but you also have a deflection angle of 45 degrees, what's the tangent length and the chainage at point T?
💡 Hint: Don’t forget to apply the right formulas carefully!
