What does a negative moment tell us about the characterisics of the airfoil?

In summary, the negative pitching moment is important because it helps to maintain aircraft stability. It is only possible with cambered wings, and is caused by the lift being concentrated on the forward of the aerofoil. It is important to keep in mind the aircraft's reference frame when studying flight dynamics, in order to avoid making sign errors.

Claim what you want, that was not your point.
It was.
I am done with this as it is going nowhere and serves no purpose.
See you later.

No, and this is the point. There is also the angular inertia, center of mass and total mass, and the moments involved in Euler buckling and torsional rigidity to obtain the radius or gyration.

None of which has anything to do with the question asked in the OP.

No. Indirectly, it does.
