Question 1.
What is the definition of a tangent in a circular curve?
Show hintHide hint
Think of it as a line that barely grazes the curve.
Question 2.
What is an intersection point?
Show hintHide hint
It's the meeting point of straight lines in a curve.
3Question 3.
What is the apex distance in a circular curve?
- Distance from curve to endpoint
- Distance from intersection to apex
- Distance around the curve
Show hintHide hint
Recall that apex is always related to the curve.
4Question 4.
True or False: The deflection angle is the angle between the two tangents at the intersection point.
- True
- False
Show hintHide hint
Remember the geometry of tangents involved.
Question 5.
A simple circular curve has a radius of 80m and sustains a deflection angle of 60°. Calculate the lengths of the tangents and apex distance using appropriate formulas.
Show hintHide hint
Break down the formulas step by step.
Question 6.
If a circular curve's central angle is 90° and the radius is 70m, find the length of the curve and the long chord.
