What does the camber line of a wing indicate?

1. The maximum thickness of the wing

2. The amount of curvature of the wing

3. The angle of attack of the wing

4. The length of the chord

The correct answer is: The amount of curvature of the wing

The camber line of a wing represents the relationship between the upper and lower surfaces of the wing, essentially indicating the curvature of the wing. It is drawn from the leading edge to the trailing edge and shows the path that lies midway between the upper and lower surfaces. The curvature of the camber line is crucial for understanding the lift characteristics of the wing; as the curvature increases, typically, the lift generated at a certain angle of attack also increases. The maximum thickness of the wing pertains to a different aspect of wing design and does not directly relate to the camber line. While the angle of attack is crucial in aerodynamics, it refers to the inclination of the wing relative to the oncoming airflow rather than the inherent shape or curvature itself. The length of the chord measures the straight line distance from the leading edge to the trailing edge, which is also separate from the concept of the camber line. Thus, identifying the camber line is specifically tied to understanding how the wing's curvature affects its aerodynamic properties.
