Which wing construction design uses internal braces to help carry stresses generated in flight?

The semimonocoque design is a wing construction that effectively uses internal braces to share and distribute the stresses experienced during flight. This design integrates both a reinforced skin and a framework of ribs or spars, allowing the structure to maintain its shape under aerodynamic loads while also providing strength through the internal support system.

The internal braces play a critical role in enhancing the structural integrity of the wing, helping to manage bending and torsional forces that occur during various phases of flight. The combination of strength and lightweight properties makes this design popular in modern aircraft, as it allows for efficient performance and increased safety.

In contrast, other designs like the monocoque do not rely on internal braces but rather utilize the outer skin to bear all the loads, which can limit the overall strength and flexibility compared to semimonocoque. The truss design, while also strong, typically involves external framework rather than integrating the structure within the skin. A hydraulic system, while crucial for many aircraft operations, does not pertain to wing design and stress distribution.
