1.A spiral 400 ft length is used for transition into a3o00' circular curve (arc deflection). Angle I at the PI station 50+0 is 60o00'. Compute and tabulate the deflection angles and chords necessary to stake out this spiral atfull sections. Given Ts = 1304.60 ft.
2.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 quetion
