curve by rankine

r=30 meters
T1=17.32m
L=30 meters
curve length=31.41meters
chainage of B=30 meters b is intersection point
chainage of T1=12.68meters
initial sub chord=7.32 meters
2nd sub chord 20 meters
last one 4.09m
small delta=(1718.9/R)length of sub chord
l ===>deflection angle from tangent (small delta)
7.32 => 419min 24 sec=>6deg 59min 20 sec
20 =>1145min56sec=>19deg6min
4.09=>234min20sec=>3deg54min20sec
diagram rankine wala deflection angle k through jo solve krte hai.
