How do bending loads behave during landing and turbulence?

Bending loads during landing and turbulence are primarily influenced by the forces acting on the wings of an aircraft. When an aircraft lands or encounters turbulence, the aerodynamic forces acting on the wings can cause them to experience significant bending moments.

The correct understanding is that these bending loads cause the wing to flex downwards due to the distribution of forces. As a result of the lift generated by the wings, along with the sudden changes in aerodynamic pressure during turbulent conditions or the impact during landing, the wing structure bends. This downward flexing is a crucial characteristic of wing design, allowing the structure to absorb and distribute these dynamic loads effectively without failing.

The behavior of bending loads is complex, as they depend on various factors, including aircraft design, weight distribution, and environmental conditions. Therefore, when understanding how wings react to loads, it is essential to recognize that the downward flexing of the wing is a primary response to the mechanical stresses encountered during flight operations.
