Challenge Problems
Push your limits with advanced challenges
Given a deflection angle of 75° and a curve radius of 100 m, calculate the tangent lengths and offsets required to set out the curve.
💡 Hint: Employ trigonometric relationships to derive the details.
If the mid-point offset on a different radius of 120 m is 15 m, determine how this changes if the deflection angle increases to 80°.
💡 Hint: Consider how angular changes can affect distances.
