According to the theory of lift, what effect does camber have on a wing?

Camber refers to the curvature of the wing's upper and lower surfaces. This curvature is essential in generating lift as it affects how the air flows over and under the wing. When a wing has camber, the air traveling over the curved upper surface must travel faster than the air below the wing, which is moving over a flatter surface. According to Bernoulli's principle, faster-moving air has lower pressure. As a result, the difference in pressure above and below the wing generates lift.

The selection that indicates that camber speeds up airflow over the wing's upper surface is correct in this context. This increase in airspeed is a fundamental aspect of how lift is created, illustrating the impact of wing design on aerodynamic performance.

Other options do not accurately reflect the role of camber. For instance, camber does not inherently decrease the wing's surface area; instead, it modifies the shape for optimal performance. Similarly, while the weight of the wing could change based on design choices, camber itself does not directly affect the weight of the wing. Lastly, while stabilization is critical in aircraft design, camber is primarily associated with lift generation rather than stabilization directly.
