What are the various elements of the simple circular curve Draw a simple curve and show the various elements?
Point of Intersection (PI)
- Intersecting Angle (I) The intersecting angle is the deflection angle at the PI.
- Radius (R) The radius is the radius of the circle of which the curve is an arc.
- Point of Curvature (PC)
- Point of Tangency (PT)
- Length of Curve (L)
- Tangent Distance (T)
- Central Angle (Δ)
- Long Chord (LC)
What are the elements of a simple circular curve give their relationship?
The elements of a circular curve required to lay it out in the field with reference to Figure 37.1 are as follows :
- Length of Curve,
- Tangent Length,
- Chainages of tangent point : The chainage of the point of intersection (V) is generally known.
- Length of the long chord (L) : Length of the long chord,
What is simple circular curve?
WHAT IS SIMPLE CIRCULAR CURVE? It is a curve consists of a single arc with a constant radius connecting the two tangents. It is a type of horizontal curve used most in common. A simple arc provided in the road or railway track to impose a curve between the two straight lines is the simple circular curve.
How do you layout simple curves by ordinates from a long chord?
Procedure:
- Find the mid point of the long chord “C”.
- Fix the other points on the curve on either side of the mid ordinate by fixing the corresponding length R2 – X2 – (R–O0) from the long chord.
- Chainage at T1 = Chainage at T1 + T1T2
What is used to draw curves that are not circular?
Explanation: French curves are used for drawing curves which can’t be drawn with a compass. A faint freehand curve is first drawn through the known points.
How do you draw a curve in Word?
Draw a curve
- On the Insert tab, click Shapes.
- Under Lines, click Curve.
- Click where you want the curve to start, drag to draw, and then click wherever you want to add a curve.
- To end a shape, do one of the following: To leave the shape open, double-click at any time. To close the shape, click near its starting point.
What are different methods for setting out of simple circular curve?
The following are some of the linear methods used for setting out simple circular curves: (i) Offsets from long chord (ii) Successive bisection of chord (iii) Offsets from the tangents–perpendicular or radial (iv) Offsets from the chords produced.
What are the elements of compound curve?
Elements of compound curve
- PC = point of curvature.
- PT = point of tangency.
- PI = point of intersection.
- PCC = point of compound curve.
- T1 = length of tangent of the first curve.
- T2 = length of tangent of the second curve.
- V1 = vertex of the first curve.
- V2 = vertex of the second curve.
