Tangential stresses in rotating ring

Next:

The sum of 10 different cross sections in bending = a displacement.

I assume i can model this as the sum of the individual sections in bending?

aka i have a shaft with 10 cross sections from one end to the middle where I have a value for amplitude. I need to find the stress in the 10th section. The total displacement is the sum of all the sections correct?

Just 10 math calculations away???

:yas!!
