Problem Set No. 5 Horizontal Curve Geometry DUE 4/21/2000 8:00am

Surveying - Transportation FE 345 Spring Quarter

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?
