3Question 3.
What is the purpose of a compound curve?
- To connect straights and curves smoothly

Show hintHide hint
Recall the definition of a compound curve.
Question 5.
A compound curve has an inner radius of 50 m and a larger radius of 70 m. Calculate the total length of the curve if the deflection angles are 30° and 45° respectively.
Show hintHide hint
Focus on calculating the lengths separately using their respective angles.
Question 6.
