Part A. The following information is for a proposed horizontal curve in a new subdivision: PI Station: 12+40.00 R-572.96 feet Deflection angle A-12.30 What is the Station of PT? PI PC PT Part B. An existing highway has a historic site located at the PT of an existing curve with a PI located at Station 80+00, an extemal angle of 65°, and a radius of 1,200 ft. The curve must be relocated, moving the PI to Station 78+00. The external...
9:381 LTE Problem 1 A crest vertical curve is to be designed to join a +2% grade with a-2% at a section of a two-lane highway. Determine the minimum length of the curve if the design speed of the highway is 60 mph and SL. Assume that a-9.34 ftsec' and that the perception-reaction time is 2.5 sec. Problem2 A crest vertical curve is to be designed to join a +3% grade with a-2% grade at a section of a two-lane...
Problem 1 (15vpts) A proposed highway has two tangents of bearings N 75° 54' 36" E and N 53° 22' 30" W. The highway design engineer, attempting to obtain the best fit for the simple circular curve to join these tangents, decides that the external ordinate is to be 78.00 ft. The Pl is at station 65+43.21. Determine: (a) The external angle of the curve (A) (b) The radius of the curve (d) The station of the PC (f) The...

I will rate your answer so please make sure the answer is accurate. The following question is a Calculus 3 problem, please answer 2) in the picture shown below, please show all the steps (step by step) and write out nicely and clearly: 1. Use Stokes, Theorem to find ls (curlF): ndS where F(x, y, z) = (y2z,zz, x2y2) and s is the portion of the paraboloid z x2 + y2 that lies inside the cylinder x2 +y-1. Use the...
