5-6. Use the method of section 5-9 to find a simple curve with equal spirals in which Ls is an exact multiple of 50ft,R is a value listed in Table V, and p is approximately 0.5. (a) I=1842;Es= approximately 27ft. Answers: Ls=200ft with R=1900ft. (b) I=3800;Ts= approximately 580ft. Answers: Ls=300ft with R=1300ft. (c) Compute deflections for staking the approach spiral in (a) as a five-chord spiral. Answers: 00225,00939,02143,03836, and 10019. (d) Compute deflections for staking the approach spiral in (b) by setting full and half-stations, assuming that sta. T.S. =60+20. Answers: 00119,00924,02450,04736,11743, and 21213. 5-6.
