WebProviding lift is the main function of the wings of an aircraft. An aircraft wing is shown in the Figure 1.4. The wings consist of two essential parts. The internal wing, structure, consisting of spars, ribs and stringers, and the external wing, which is the skin. The internal structure of an aircraft wing is shown in the Fig 1.5. Web21 Jan 2024 · The main spar has to carry the loads imposed on a cantilever wing. Those loads include both vertical and horizontal shear, along with bending moment. The torsional (twisting load) on the wing is another one to consider. Of those loads, vertical shear imparts the least amount of stress on the spar, followed by lateral shear.
