Q: The curve that is generally used to avoid the obstructions like hard rocks, deep cuttings, soft gradients is called _________.
  • A. compound curve
  • B. simple curve
  • C. transitional curve
  • D. parabolic curve
Correct Answer: Option A - compound curve:- A compound curve is a combination of two or more simple curves with different radii joined together to form a smooth transition. It is commonly used in road and railway engineering to navigate around obstacles like hard rocks, deep cuttings or soft gradients, ensuring a safe and gradual change in direction or elevation.
