Two tangents having azimuths of 240 deg. And 282 deg. Are connected by a spiral curve with 191m radius of circular curve. The width of the roadway is 15m. If the design velocity is 75kph, determine the following. а. Determine the length of the spiral curve. b. Determine the length of the external distance. С. What is the rise of the road in circular curve at its outer side with reference to its inner side?

FULL SOLUTION PLEASE. DO NOT ROUND OFF PLEASE.The common tangent BC of a reverse curve is 281 m and has an azimuth of 311 degrees . AB is tangent of the first curve whose azimuth is 250 and a distance of 320 m while CD is tangent of the second curve whose azimuth is 211 degrees and a distance of 301 m. If the radius of the second curve is 190 m, determine the following:A. radius of the first curveB. length of the curve from PC to PT

6) A horizontal curve is to be designed on a 2-lane road on a mountainous terrain. The flowingdata are known: Δ= 40 deg, T = 436.76’, station of PI: 2700+10.65, fs = 0.12, and e = 0.08.Determine the following:a) design speedb) station of the PCc) station of the PTd) deflection angle to the first 100’ statione) chord length to the first 100’ station
