Question 1.
What is a deflection angle?
Show hintHide hint
Think about how two paths diverge.
Question 2.
Define 'offset' in the context of circular curves.
Show hintHide hint
Consider how you would measure from a straight line to a curve.
3Question 3.
What does the deflection angle represent in curve design?
- A straight line measurement
- The angle between two tangents
- The radius of the curve
Show hintHide hint
Think about how paths transition geometrically.
4Question 4.
True or False: The midpoint of a curve is the same as the beginning of the tangent.
- True
- False

Visualization of curves will help clarify this.
Question 5.
Given a deflection angle of 75° and a curve radius of 100 m, calculate the tangent lengths and offsets required to set out the curve.
Show hintHide hint
Employ trigonometric relationships to derive the details.
Question 6.
If the mid-point offset on a different radius of 120 m is 15 m, determine how this changes if the deflection angle increases to 80°.
Show hintHide hint
Consider how angular changes can affect distances.
