Show hintHide hint
Remember, T stands for tangent length.
Question 2.
If you have a deflection angle of 180° and a radius of 200 m, what would be the length of the curve?
Show hintHide hint
Use the provided formula for length of curve.
3Question 3.
What does the tangent length (T) depend on?
- Radius and chainage
- Deflection angle and radius
- Sub-chord length
Show hintHide hint
Think about how tangents are set up in circular curves.
4Question 4.
Chainage is important for:
- True
- False
Show hintHide hint
Consider its definition and application in layout.
Question 5.
You have a curve with a radius of 100 m and a deflection angle of 40°. Calculate the total vertical space needed to create the tangent.
Show hintHide hint
Utilize the trigonometric functions associated with the circle.
Question 6.
In a project with two curves, the first has a radius of 150 m and the second of 250 m. Analyze the tangential lengths needed to connect the two points of a circular endpoint.
Show hintHide hint
Link the tangential lengths back to the necessary computations.
