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.
