Simple Curves
A simple curve is a horizontal curve formed by one continuous circle, used to change the direction of an alignment gradually instead of abruptly at an intersection of straight lines.
A simple curve is a horizontal curve formed by one continuous circle, used to change the direction of an alignment gradually instead of abruptly at an intersection of straight lines.
A simple curve connects two tangents, AB and BC, with bearings of N76ºE and S63ºE, respectively. If the stationing of the vertex is 3+988 and the stationing of PC is at 3+866, determine the stationing of a point on the curve which intersects with the line making a deflection angle of 6º with the tangent passing through the PC.

If the stationing of the vertex is 3+988 and the stationing of PC is at 3+866, determine the offset distance of a point on the curve which intersects with the line making a deflection angle of 6º with the tangent passing through the PC.
If the degree of simple curve whose central angle is 26º is 6º, determine the area of the fillet of curve in m2. Use arc basis and S.I. units.
A simple curve has an angle of intersection of 30º. If the middle ordinate is 16m, determine the radius of the simple curve.
A simple curve has a degree of curve of 5º. If English Units are to be used, determine the length of chord (in ft) if I=36º. Use chord basis.
The offset distance of the simple curve from the PT to the tangent line passing through the PC is equal to 126.2m. The stationing of PC is at 2+978. The simple curve has an angle of intersection of 26º. Determine the stationing of PT.
