Question 1.
What is an offset in the context of setting out curves?
Show hintHide hint
Think about the relationship between a straight line and the curve.
Question 2.
How do you find the offset at the midpoint of a long chord?
Show hintHide hint
Recall how the midpoint divides the chord.
3Question 3.
What is the primary aim of using ordinates in curve setting?
- To establish straight lines
- To measure distances only
- To reliably determine points on curves
Show hintHide hint
Focus on the function of ordinates in the context of curves.
4Question 4.
True or False: The offsets for a circular curve can vary significantly from left to right.
- True
- False
Show hintHide hint
Think about the properties of symmetry in curves.
Question 5.
Given a radius of 80m and a long chord of 60m, calculate the offset at each of the four divisions of the chord.
Show hintHide hint
Break it down; remember the chord is divided evenly.
Question 6.
Discuss how the curve’s diameter influences the respective offsets calculated at various distances.
Show hintHide hint
Consider how increased radius changes the geometry of the curve.
