Situation 4X - 6Y - 9Z - 7 Situation 1] A circular road is proposed to be laid out with tangent AB whose bearing isN8Z°54'E intersecting another tangent line BC whose bearing is N4Y030'E. If the degree of thecurve is 4.5°, using arc basis, determine the following:i.Tangent distance of the curve, Tii.Long chord of the curve, CMiddle ordinate, MExternal distance, ELength of the road, LCIf the station of point B 10+XYZ, determine the station of PT.ii.iv.V.vi.Situation 2] A simple curve having a radius of 23Z.0 m has tangents of N28.X°E and N66.0°E. Aline running parallel to the first tangent crosses the centerline of the curve at a distance 10meters away from the first tangent. If chainage of station PC is 17+ZYX,i.What is the deflection angle at the point of intersection of the line and the simplecurve measured from PC?ii.What is the chainage of the point of intersection?ii.Compute the chord distance from PC to the point of intersection of the line and thecurve.Situation 3] The bearing of the first tangent of a simple curve is N70.X°E while the secondtangent has a bearing of S82°3Z'E. The degree of curve is 4.5° and chainage of PC is 3+XY. Itis proposed to decrease the central angle by an angle of 7° by changing the direction of thesecond tangent, in such a way that the position of PT and the direction of the first tangent shallremain unchanged. Determine the following:i.New angle of intersection, I'.ii.New radius of the curve, R'.ii.New chainage of station PC.Situation 4] Two tangents that intersect at an angle of 4X°40' are to be connected by acompound curve consisting of a 4.1° curve and a 5.5° curve. If the tangent at the beginning ofthe curve to the point of intersection of the tangent is 110 m long,i.Compute the central angle of the first curve, lı.ii.Compute the central angle of the second curve, l2.ii.Compute the length of the tangent from the end of the 5.5°-curve to the point ofintersection of the tangents.
