The torque distribution along a wing arises from

  • A.The fuselage pressurisation
  • B.Lift offset from the flexural axis
  • C.The wing's bending moment alone
  • D.The engine thrust only

Answer: B

Each spanwise strip contributes a torque equal to its lift times the distance from the section's shear centre. Accumulating those contributions inward gives the torque the box must carry at each station, and control surface loads add to it.
