What is the primary tool used in linear methods?
Consider the basic tools for measurements.
Name two methods for setting horizontal curves.
Think about the types of methods discussed.
Which method relies primarily on chains and tapes?
Consider the simpler toolset used.
True or False: The deflection angle is simply the intersection angle.
Think about how angles are defined in curve setting.
A curve requires a 30m radius. If the intersection angle at point B is 90°, calculate the tangent lengths and deflection angle required for setup.
Use the tangential formula for computing lengths.
You have two methods available for a project. How would you decide the appropriateness of each in setting curves for high-speed rail versus a local road?
Evaluate the context and speed requirements of the vehicles involved.
