Question
the p.c of 3 degree curve whose degree is base on 100ft chord is at sta 7 +60. if it desired to locate sta 7+60. if it is dessire to locate 10+00 by the method of tangent offset the cordinate ofsta 10+00 with respct to the tangent at the p.c will be wich one is it is A x=239.32 ft y=15.01 is it B x239.36., y=15.07 ft is it C x=239.42., y=15.01 or is D x=239.42., y=15.01 on the same quetion if the degree of curve is base on a100ft arc, the coordination of sta.10+00 would be wich one is it is A x=239.36 y=15.01 or is it B x=239.36 ft., y=15.07 or is C 239.42ft., y=15.07 ft or is D x= 239.42 ft., y =15.01 ft can you tell me wich one quetion is right on both quetionExplanation / Answer
Since I am only a 2nd year civil student, I can only offer so muchhelp. I would say your best bet is to search up highway curves online sothat you can understand the concepts before you tackle theproblem. PC has 3 degree curve -- 100 ft chord -- 7+60 Use surveying techniques by first drawing a picture Then I assume you will need to use the equation for radius ofcurvature Hope this helps some, If you have any questions, send me a message.
