Hi BP, my great pleasure. I got a surveying problem that is really smashing my bearings!! Go to
. No diagram is given and curve length,L,to find. When able if you can kind of get me started in the right direction that would be cool. Almost all of the textbook vert. curve probs include L. Thanks much.
Hi
I want to say your message and good results were a great help to me in advancing my CN skill. I used your results to confirm that I was doing this type of sight reduction and analysis correctly. I usually use HO 249 and check results with trig equations.
I could not get your exact results and I knew the error had to be in my use of the tables. Finally I asked Mike Burkes for help and he explained that you used LL .....then perfect agreement. As Mike wrote to me LL is far easier than using coincident images. Then just use normal procedures and tables. A public thanks to Mike.
Bruce
