In wing design, what does the term "camber" refer to?

1. The angle of the wing relative to the airflow

2. The distance from the leading edge to trailing edge

3. The curvature of the wing surface

4. The length of the wing’s chord

The correct answer is: The curvature of the wing surface

Camber refers to the curvature of the wing surface and plays a significant role in aerodynamic performance. More specifically, it describes the asymmetrical shape of the wing where the upper surface is curved more than the lower surface. This curvature changes the flow of air over the wing, which can increase lift during flight. A wing with positive camber will generally provide more lift at lower speeds compared to a flat wing. The other options relate to different aspects of wing design: the angle of the wing relative to the airflow, the distance from the leading edge to the trailing edge, and the length of the wing’s chord do not define camber itself but are instead components or characteristics associated with the overall design and aerodynamics of the wing.
