What defines a cantilever wing?

• A. It requires external support for stability
• B. It has no external braces or wires
• C. It relies solely on the fuselage for support
• D. It is heavier than traditional wings

Answer: (B)

A cantilever wing is characterized by its design that does not require external braces or wires for support. This type of wing relies on its own structural integrity to bear the loads imposed during flight. The structure is built in such a way that it can transfer the aerodynamic and weight loads without needing additional support. This design allows for a cleaner and more aerodynamic shape as there are no external supports that would disrupt airflow around the wing.

The use of cantilever wings is common in modern aircraft as it provides advantages in terms of efficiency, weight, and aesthetics. The absence of external braces minimizes drag and enhances the aircraft's performance. Consequently, this wing design is favored for providing a sleek appearance and improving overall aerodynamic efficiency.
