As per the given curvature, the value of PC is 1785.68 and PT is 1787.55
Curvature:
In statistics, curvature means amount by which a curve deviates from being a straight line, or a surface deviates from being a plane.
Given,
PI is at station (20 00), the radius of curvature is 800 feet, and the angle of curvature is 30 degrees.
Here we need to determine the value of PC and PT.
According to the given value, the tangent distance is calculated as,
=> T = 800 x tan (30/2)
=> T = 800 x 0.2679
=> T = 214.32
Now, the value of PC is calculated as,
PC = PI - T
=> PC = 2000 - 214.32
=> PC = 1785.68
And the value of PT is calculated as,
PT = PC + L
=> PT = 1785.68 + (100 x (30/1600))
=> PT = 1785.68 + 1.875
=> PT = 1787.55
