Question 1.
What is the purpose of setting out circular curves in civil engineering?
Show hintHide hint
Think about construction projects.
Question 2.
Define 'offset' in the context of setting out curves.
Show hintHide hint
Consider how a curve relates to straight lines.
3Question 3.
What is the first step in the method of successive bisection of arcs?
- Join endpoints
- Calculate lengths
- Bisect chords
Show hintHide hint
Think about how a curve starts.
4Question 4.
True or False: Ordnates are used to measure distances perpendicular to the curve.
- True
- False
Show hintHide hint
Think of how you would position a curve with respect to a straight line.
Question 5.
During the construction of a new bypass, engineers must set out a circular curve with a radius of 60 meters. If the angle subtended at the center is 60 degrees, calculate the total offset using the versine method.

Double-check your angle conversion:
Question 6.
A road engineer encounters rocky terrain, making traditional curve setting challenging. By applying the successive bisection of arcs method and starting with a straight section of 80 meters, demonstrate the steps involved in laying out the curve.
