What is a characteristic of a cantilever wing?

A cantilever wing is designed in such a way that it projects out from the main structure without the need for external bracing or supports. This characteristic allows for a cleaner aerodynamics profile and minimizes drag, making the wing structure more efficient. By utilizing internal structural elements such as spars and ribs, the cantilever wing can effectively support itself under load while maintaining its shape and integrity during flight. This design feature is particularly beneficial for modern aircraft, where minimizing weight and maximizing aerodynamic efficiency are key considerations in engineering.

The other options address characteristics that do not apply to cantilever wings. For example, requiring multiple support beams would contradict the very nature of a cantilever design, which is self-supporting. Additionally, a cantilever wing is specifically engineered to maintain its shape under load, making it quite capable of withstanding aerodynamic forces. Lastly, while wind resistance is a consideration in wing design, the cantilever configuration is generally intended to reduce drag rather than increase it. Hence, the defining characteristic of a cantilever wing is that it operates efficiently without the need for external bracing.
