Question 1.
What is a transition curve?
Show hintHide hint
Think about how roads bend.
Question 2.
What does 'h' represent in the super-elevation formula?
Show hintHide hint
It is a measurement related to angles.
3Question 3.
What is the formula for the length of a transition curve based on super-elevation?
- L = n * h
- L = h / n
- L = h + n
Show hintHide hint
What do you need to multiply?
4Question 4.
True or False: Radial acceleration for a curve should exceed 30 cm/sec² for better safety.
- True
- False
Show hintHide hint
Think about what level keeps passengers comfortable.
Question 5.
A highway is designed with a radius of 200 m and a vehicle speed of 50 m/s. Calculate the necessary transition curve length assuming the maximum radial acceleration is 25 cm/s².
Show hintHide hint
Use the relationship between motion and curvature.
Question 6.
A railway track has a super-elevation of 6 cm. If the curve applies super-elevation uniformly with a rate of 1 in 500, determine its transition curve length.
Show hintHide hint
Think about the direct proportionality in the rates.
