The wing of an aircraft in flight, powered by engines located under the wing, is subjected to a bending moment which causes its leading edge, from the wing root to the wing tip, to operate in:

1) Flutter results from two deformation modes which are:

2) In flight, a cantilever wing of an airplane containing fuel undergoes vertical loads which produce a bending moment:

3) Torsion in a wing can be caused by:

4) When do you say that an aircraft has a cantilever wing?

5) The wing of an aircraft in flight, powered by engines located under the wing, is subjected to a bending moment which causes its leading edge, from the wing root to the wing tip, to operate in:
