Design a compound curve between two straight sections connected by tangents of lengths 40m and 30m. The radii are 50m and 60m with deflection angles 25° and 35°. Calculate the lengths of each arc and set out the angle measurement.
💡 Hint: Convert angles to radians before multiplication with radii.
A road engineer needs to determine the tangent point location between two straight roads intersected by a compound curve. Given the straight lengths and angles, devise a solution for locating point B.
💡 Hint: Draw a diagram to visualize locations based on angles.
