See you later.I am done with this as it is going nowhere and serves no purpose.

Phrak said: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.

A negative moment is a force that causes the airfoil to rotate in a clockwise direction, as viewed from above. It is also known as a "pitch-up" moment, as it causes the nose of the airfoil to rise.
A negative moment reduces the lift generated by the airfoil. This is because it causes the airfoil to rotate in a way that decreases the angle of attack, which is the angle between the airfoil and the incoming airflow. A lower angle of attack means less lift is produced.
Several factors can contribute to a negative moment on an airfoil, including the shape and design of the airfoil, the angle of attack, and the speed and density of the air flowing over the airfoil. Additionally, any external forces acting on the airfoil, such as weight or wind gusts, can also contribute to a negative moment.
In some cases, a negative moment can be beneficial for an airfoil. For example, in certain aerodynamic designs, a negative moment can help to stabilize the airfoil and improve its performance. However, in most cases, a negative moment is undesirable as it reduces lift and can lead to instability.
To minimize negative moments on an airfoil, engineers can make adjustments to the design and shape of the airfoil, as well as the angle of attack. Additionally, using control surfaces, such as flaps and ailerons, can help to counteract negative moments and improve the overall performance of the airfoil.
