Cards in this deck (9)
- 1Tangent pointsTP1 and TP2 are the tangent points where the circular curve touches the straights
- 2Intersection pointI is the intersection point of the two
straights
- 3Tangent DistanceTP1–I & TP2-I are the Tangent distance
- 4Circular curve (arc)TP1–P-TP2 is the circular curve (Arc)
between the two tangent points
- 5Circular Curve (arc) contd.Lc is the length of the circular curve = Arc
Length
P is the mid-point of the circular curve - 6Long ChordS is the mid-point of the long chord
PS is Height of Long Chord
- 7Deflection angle ββ = Deflection Angle
+ = right hand curve
- = left hand curve
- 8RadiusR is the Radius of Curvature of the circular
curve
- 9External distanceExternal Distance = PI
