Advanced Geomatics: Horizontal Curves: Example 2: Part 1

[@GenaEnSamIAm]

Hi there, should you not have converted to radians first?

[@sonnys3749]

whats happening to get the R? Im lost in this process and its the difference between the right answer and wrong answer in the end. Whats happening in sin angle/2? I converted to decimal? still not the right answer??

[@markrodriguez4663]

Can you go over how to solve the problem to get the radius? For some reason it's not working when I do it. Thanks.

[@kendayamo478]

where did you got the Lc 100

[@hitomiflyingturtle5496]

1 station = 100 ft.

Any chance you could walk me through your solving for R process? Maybe its because im Canadian but Im having trouble quite solving for R in the 642.005 = 2(R)Sin(25 52'41"/2)

[@yengher1983]

it woulda been helpful if you showed your work on how you solved for LC because I can't understand how you just got the solution for R without the work.

[@SurveyGuy-j2d]

The right answer is: 1433.0468
you divide 642.005/2=321.0025 this is your opposite side, Sin(12.9473)=Op/H , H=Op/sin(12.9473), H=321.0025/.2240, H=1433.0468, R=1433.0468. Please correct me if I'm wrong

y do u need to complicate things

[@webnest5705]

Use the whole digits on you calculator to git the exact number

ty my dought solved

[@nasirahmad5426]

Dear you use the wrong formula for the degree of curve you here use length of cord instead of length of the curve

[@SavasPapasokratis]

ikr

[@keshavreddy9787]

For flat curves length of long chord is equal to length of curve

[@elnasisimo]

haha "That is a really nice blue!"

D=5729.58/R
