Problem 1

Given DELTA = 43°05' and E = 172 ft (approx).  What is the degree

of curve?                                                                                                        

 

Problem 2

If DELTA = 30°12' and D = '2°48', find T and L.                                          

                                                             

Problem 3

Using the data of Prob. 2 and assuming the PI to be at Sta.                                                          

42 + 16.6, what is the correct number for the PT?                                                                       

                                                             

Problem 4

If the radius of a curve is 4,000 ft, calculate the deflection angle                                                

for a 40-ft arc                                     

                                                             

Problem 5

What is the middle ordinate M  for an arc of 100 ft, which sub-                                                 

 tends a central angle of 8°00' ?

                                                             

Problem 6

Given D = 6°00' (arc definition) and the PC at Sta. 21 + 00.                                                      

With reference to the PC and the initial tangent, what are the coordinates x and y locating Sta. 23 + 00?
