The primary function of a wing rib is to

  • A.Attach the wing to the fuselage
  • B.Maintain the section and stabilise the skin
  • C.Carry the wing bending moment
  • D.Carry the wing torsion by itself

Answer: B

Ribs hold the section to its aerodynamic shape, divide the skin into shorter panels so it buckles at a higher load, and pass the air load into the spars. They also stop the spar webs and caps from failing by lateral instability.
