Camber refers to which aspect of the wing?

• A. The curvature of the wing's mean line
• B. The wing's material composition
• C. The wing's dihedral angle
• D. The wing's sweep angle

Answer: (A)

Camber is the curvature of the airfoil's mean line—the line that runs halfway between the upper and lower surfaces along the chord. This curvature makes the airfoil asymmetric, which helps generate lift at lower angles of attack and gives a negative zero-lift angle for positive camber. A symmetric airfoil has zero camber, meaning no curvature of the mean line. The other terms describe different features: material composition, the vertical tilt of the wing (dihedral), and the backward-slanted leading edge (sweep). So the correct description is the curvature of the wing's mean line.
