In a glider wing, which camber statement is true?

In a glider wing, which camber statement is true?

• A. The camber is greater on the lower surface than the upper
• B. The camber is greater on the upper surface than the lower surface
• C. The camber is equal on both surfaces
• D. The camber doesn't affect pressure distribution

Answer: (B)

Camber is the difference in curvature between the wing’s upper and lower surfaces. When the upper surface is more curved than the lower, air must speed up as it flows over the top, creating a region of lower pressure there while the bottom remains relatively higher in pressure. This pressure difference generates lift. In this case, having greater camber on the upper surface is the scenario that produces that favorable pressure distribution and lift at typical glider angles of attack, making it the true statement. If the camber were greater on the lower surface or the surfaces were equal, the lift and pressure distribution would be less favorable for sustained flight at lower speeds, and camber is indeed what shapes how pressure is distributed around the wing.
