(a) Railroad curve with Dc = 4°00(, I = 24°00(, and PI station = 36 + 45.00 ft.
(b) Highway curve with Da = 2°40(, I = 14°20(, and PI station = 24 + 65.00 ft.
(c) Highway curve with R = 500.000 m, I = 18°30(, and PI station = 6+517.500 m.
(d) Highway curve with R = 750.000 m, I = 18°30(, and PI station = 12+324.800 m.
Compute L, T, E, M, LC, R, and stations of the PC and PT for the circular curves in the following problems. Use the chord definition for the railroad curve and the arc definition
for the highway curves.
