3 cards from this section. Quick, good the night before a test.
Define curvature and give an example.
Think about how easily a vehicle can navigate.
What does chainage indicate?
It helps in locating specific points on roads.
What is the formula for the length of a circular curve?
Remember how we calculate curve length.
The tangent length decreases as the radius increases.
Think about the geometry of circles.
Design a curve for a road segment intersecting at an angle of 90 degrees, incorporating a radius of 100 m. Calculate tangent and curve lengths.
Remember to check angle measures during calculations.
If a road has a chainage of 500 m at the intersection and a tangent length of 40 m, what is the chainage at the start of the curve?
Visualize the intersection to visualize where points fall on the curve.
