PROBLEM 1: Given a highway curve with Da = 2°30', I = 10°30', and PI station = 36 +44.50 ft. Determine the deflection angle at station 37+00. Can use Wolfpack. Given information: Intersection Angle = 10°30'00" Degree of Curvature = 2°30'00" Radius = 2,291.83 Your text here 1 Circular Curve Length = 420.00 Tangent Distance = 210.59 Circular Curve Long Chord = 419.41 Middle Ordinate = 9.61 External = 9.65 PI Stationing = 36+44.50 38+53.91 Back = 38+55.09 Ahead Station Chord Defl.

Calculate R, L, and the stations of the PC and PT. V 25+00.00 20'26' 35'30' 550.00 1 B C 5 PT Y Hints: Combine (Add) I's. Find R with Equation 24.4 in terms of both I/2 angles with a combined T = 550.00 ft. Use a PI = 27+31.79 ft. Solve with Wolfpack. PC
