#1

Four simple cuve(curve1,curve2 & curve3) are connected to the highway curves. curve2 formed a compound curve withe curve1. curve2 also formed a reverse curve with curve3. the common tangent of the compound curve is parallel to its long chord. the reverse curve has parallel tangets.

curve1 radius= 800m

curve1 long chord=170m

curve1 stationing of pi = 9+578.40

curve2 radius = 520m

curve2 long chord = 135m

curve3 radius = 750m

curve3 long chord = 221 m

 

#2

using arc basis, compute the following and answer the following qustions:
