5 Questions
Explain the purpose of curves in lines of communication and how they are connected to straight lines or tangents.
Curves are used to ensure gradual change of direction at the intersection of straight lines, and they are connected to straight lines or tangents by being tangential to them.
What is the necessity of providing curves in alignment and how do they prevent excessive cutting and filling?
Curves in alignment prevent excessive cutting and filling by making the change in alignment gradual and by providing diversions to avoid obstructions on the straight route.
Describe the types of curves mentioned in the text and provide a brief explanation of each.
The types of curves mentioned in the text are simple curve, compound curve, reverse curve, transition curve, and lamniscate curve. Each type has its own unique characteristics and purpose in alignment design.
What is a simple circular curve and how is it represented?
A simple circular curve consists of a single arc connecting two tangents or straights. It is usually represented by the length of its radius or by the degree of curve.
Explain the concept of a compound curve and how it differs from a simple circular curve.
A compound curve consists of two arcs of different radii curving in the same direction and lying on the same side of their common tangent, with their centers being on the same side of the curve. This differs from a simple circular curve, which consists of a single arc connecting two tangents or straights.
