A 900 ft radius curve is stationed from its PI, with the 29.63 ft of chainage lost at the corner made explicit and every full station on the curve tabulated.
Recall· about 16 minutes by hand· 5 steps
Given
A simple circular curve with R = 900.00 ft and Δ = 41°18′00″.
Station of the PI = 87+42.36.
Alignment stationing runs ahead through the curve; there is no station equation on this alignment.
All distances are US survey feet.
Required
The stations of the PC and the PT.
The chainage difference between the true PT and the incorrect PI plus T.
The arc distance from the PC to each full station lying on the curve.
