Aerospace Structures • Thin-Walled Structures • Shear Flow in Open & Closed Thin-Walled Beams
In a symmetric thin-walled single-cell aircraft wing box subjected to pure transverse shear load through its shear center:
(A) The rate of twist d heta/dz is identically zero
(B) The shear flow is zero everywhere
(C) Direct normal bending stresses are zero
(D) The box undergoes pure torsional rotation without bending
Answer Key:
A
Step-by-Step Verified Solution
### Solution: By definition of the shear center, applying a transverse shear load through the shear center produces pure flexural deflection with zero torsional rate of twist (d heta/dz = 0). Correct: A.
