1.4. Peg Interval

Try these first

1. 1.

   What is a peg interval?

   Hint

   Remember it relates to placing markers.

2. 2.

   What does chainage refer to?

   Hint

   Think about how distance is measured.

3. 3.

   What is the peg interval?

   • Distance between two points
   • The distance between two pegs
   • Angle of deviation

   Hint

   Think about how pegs are used in surveys.

4. 4.

   A radius of 150 m with a deflection angle of 30 degrees yields what tangent length?

   • 65.00 m
   • 40.00 m
   • 60.00 m

   Hint

   Make sure to apply the formula correctly.

5. 5.

   You are tasked with setting up a curve with a total length of 1000 m, a radius of 200 m, and a deflection angle of 45 degrees. Calculate the total number of pegs required and their respective chainages.

   Hint

   Use both the radius and deflection angle to find necessary lengths.

6. 6.

   Design a survey that involves calculating peg intervals when given a complex curve with varying radii at distinct chainages. Demonstrate all calculations.

   Hint

   Utilize formulas for each section of the survey to create an effective plan.
