Which wing type requires both internal bracing and external support from struts?

1. Semi-Cantilever Wing

2. Monoplane Wing

3. Biplane

4. Fully Cantilever Wing

The correct answer is: Semi-Cantilever Wing

The correct answer is the semi-cantilever wing. This type of wing design indeed relies on both internal bracing and external support from struts for structural integrity. The internal bracing provides reinforcement to the wing's structure, while external struts help to distribute the loads and stress experienced during flight. In contrast, a fully cantilever wing is designed to be self-supporting without the need for external struts, relying solely on the strength of its internal structure. Monoplane wings typically feature a simple design with less complexity than a semi-cantilever wing, while biplane wings involve two wings stacked one above the other and usually do not require both internal and external support in the same way. Therefore, these other wing types do not fit the criteria of requiring both forms of support as effectively as the semi-cantilever wing does.
