Challenge Problems
Push your limits with challenges.
Question 1
A circular curve with a deflection angle of 60° joins two straights. Given the radius is 400 m, calculate the lengths of the tangents and the long chord.
💡 Hint: Use trigonometric identities to find the lengths.
Question 2
In a design for a roadway, a simple circular curve needs to accommodate traffic at a speed of 80 km/h. Calculate the necessary radius, considering a maximum allowable lateral acceleration.
💡 Hint: Remember the safe turning radius at higher speeds.
