Which statement about a cantilever wing design is true?

In a cantilever wing design, no external bracing is needed because the structure itself is designed to withstand the aerodynamic loads internally. The wing's design typically includes sturdy spars and ribs that provide the necessary strength and stiffness to support the wing's weight and resist bending moments during flight. This allows for a clean, unobstructed wing surface which is crucial for maintaining aerodynamic efficiency.

Additionally, the absence of external bracing contributes to a reduction in drag, enhancing the aerodynamic performance of the aircraft. This streamlined profile is advantageous for various flight conditions, making the cantilever wing a popular choice in modern aircraft design. The other considerations, such as construction costs or aerodynamic factors, do not inherently affect the fundamental characteristic of a cantilever wing's bracing requirements.
