On the stable posture of a triangular or a square cylinder about its central axis in a uniform flow

The statistically stable posture of a triangular or a square cylinder is experimentally studied when it is free to rotate about its central axis fixed perpendicular to a uniform flow. Both cylinders come to rest in a stable posture with a side perpendicular to the uniform flow.
