Video 5. Flexible fiber injected in a parabolic flow.
Video 6. Flexible fiber injected in between two plates moving in opposing directions.
In Video 6, the fiber is placed between two plates, each one moving in a different direction. If the
drag were computed based on the centroid of the fiber, it would not move, as the fluid velocity
is zero at the center. But as the drag is computed per segment, the fiber rotates.
