A large polar moment of inertia was the main driver for me choosing to investigate Tensile Rotary Power Transmission using large diameter rigid rings (polygons now) and multiple connecting lines.

How do wings work?
Holger Babinsky
Department of Engineering, University of Cambridge, Cambridge CB2 1PZ, UK

Abstract
The popular explanation of lift is common, quick, sounds logical and gives
the correct answer, yet also introduces misconceptions, uses a nonsensical
physical argument and misleadingly invokes Bernoulli’s equation. A simple
analysis of pressure gradients and the curvature of streamlines is presented
here to give a more correct explanation of lift.
