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
To anticipate the dip and the hump in the road, the driver of a car applies his brakes to produce a uniform deceleration. His speed is 100kph at the bottom A of the dip and 50 kph at the top C of the hump. The length of the road from A to C is 120m. The radius of curvature of the hump at C is 150m. The total acceleration at A is 3 m/s^2. Compute the radius of curvature at A.
Question 14 A blind horizontal curve has a length equivalent to 54 meters. If the the design sight distance is equivalent to 67 meters, and the middle ordinate is equivalent to 8.2 meters, Calculate the minimum radius of the curve so it can be classified SAFE. • Question 16 A vehicle traverses a superelevated curve at 52 kph. If the radius of the curve is 64 meters, and the coefficient of friction is equal to 0.3, calculate the angle of superelevation (0) as measured from the horizontal.
