prop shaft

To IAN,

Shaft is conecting gear box RPM from engine to propeller.
Bending:
Overhung Moment (propeller weight): 103.1155 lbf X 4 G X 3.995inches
Propeller Gyroscopic Moment: 18 700.7 in-lbf
Propulsive Thrust: 2758 lbf
Torque: 18 372 in-lbf

My task is to define stress graph in the flange with .050 step inmachining between shaft and flange.
