ans No. 3 only. asap
PROBLEM 1. The long chord of a compound curve is 120m long which makes an angle of 14° from the tangent of the first curve passing through the PC and 20° from the tangent of the second curve passing through the PT. If the common tangent is parallel to the long chord. a.) Compute the length of chord from PC to PCC b.) Compute the length of chord from PCC to PT c.) Compute the difference in radius of the first and second curve. PROBLEM 2. A compound curve passes thru a common tangent AB having a length of 300m. The radius of the first curve is equal to 290m and a central angle of 42°. If the angle of intersection of the curve is 70°36'. a.) Compute for the Radius of the second curve b.) If the stationing of the PI is at (20+542.2), Compute for the Stationing of PT. PROBLEM 3. Two parallel tangents 20m apart are to be connected by a reversed curve with equal radius. The tangent of the 1st curve is 37.817m which is along the tangents of common direction. The stationing of the PC is 10+200. a.) Compute for the long chord. b.) Compute for the common radius. c.) Compute for the stationing of PT.
