5.1. Two straights intersect

Try these first

1. 1.

   Define what a chainage point is.

   Hint

   Think about how you measure distance on a path.

2. 2.

   What is the formula for calculating tangent length?

   Hint

   Remember how angles and tangents relate to circles.

3. 3.

   What is a chainage point?

   Hint

   Think about measuring distances in construction projects.

4. 4.

   True or False: A higher deflection angle means a sharper curve.

   Hint

   Visualize bends in a path.

5. 5.

   Design a roadway section where two roads intersect at 60 degrees with a radius of 500 m. Calculate maximum tangent lengths and chainage points.

   Hint

   Use the tangent formula and visual aids.

6. 6.

   Propose a scenario where incorrect radius selections lead to safety issues on the road.

   Hint

   Reflect on past examples or case studies.
