calculating the torque of particle structure in am fluid flow

The structure looks like a pearl necklet with fixed joints like they are welded together. It has linear and angular velocity. many forces are acting on the structure due to the fluid stream. Now I want to calculate the torque at every joint. My Idea is:

  1. calculating the net force resulting from the forces of the stream.
  2. with this, calculate the angular acceleration at every joint.
  3. determine the inertial tensor at the joints.

--> 4. calculating the torque at every joint.

I need your help! Is this a valid possibility or am I doing nonsense? applied mechanics is not one of my best subjetcs :-)

Please answer me!

Regards, sirdom
