Quickly please I need help please 1. A sag vertical curve is shown below:BVCEVCSta 24+50Sta 19+50-3.2%+2.4%EVİSta 22+00; Elev 700.28 fta) At what station is the low point located?b) What is the elevation of the low point?c) What is the elevation of station 21+25.04?d) Based on comfort, what is the highest design speed for this curve?e) What is the rate of grade change per station?f) If 20 ft of clearance are required, what is the lowest elevation that the bottom of anoverhead deck may have at station 23+16?2. A car is travelling up a 1.25% grade of a crest curve with a design speed of 40 mph. Thedescending grade is -2.75%. What is the required length of curve for minimum properstopping sight distance?3. A circular curve is to be constructed with a 225 ft radius and an intersection angle of55o. The separation between stakes along the arc is 50 ft.(a) Determine the chord lengths between stakes.(b) Assuming the curve is laid from point to point; specify the first and last deflectionangles.(c) Determine the lengths of the first and final chord.
