Challenge Problems
Push your limits with advanced challenges
A compound curve has two arcs with radii of 400 and 600 meters respectively. If the first arc has a deflection angle of 50 degrees, calculate the total length of the curves using the given radii and angles.
💡 Hint: Use the formula for curve length for each arc and sum them.
If the tangent at the point of intersection is 100 m long and the chainage at the PI is 2000 m, determine the chainage at the start of the curve.
💡 Hint: Subtract the tangent length carefully from the point of intersection.
