Given a radius of 150 m and a deflection angle of 37°, calculate the curve length and tangent length. Then calculate the chainages based on apex chainage of 2000 m.
💡 Hint: Remember to convert degrees to radians for the correct calculation!
A curve with a deflection angle of 30° needs to have its chainage calculated at two points – one at 200 m and another at 250 m from the apex chainage of 1800 m. Calculate both.
💡 Hint: Focus on the form of calculation to see how changes affect your outcomes!
