Challenge Problems

Push your limits with challenges.

Question 1

You are tasked with setting out a circular curve with a radius of 15m. If your first tangent point is 5m away from the beginning of your curve, calculate the offsets for each meter along the chord up to 10m. Show your computations.

💡 Hint: Consider what happens as x increases—how do the offsets behave?

Question 2

Using the Versine method, explain in detail the steps needed to set out a curve on uneven terrain where ground measurements vary in difficulty.

💡 Hint: Focus on the importance of reliability of offset calculations in relation to terrain.
