Aerospace Structures • Thin-Walled Structures • Shear Flow in Open and Closed Thin-Walled Beams
For an open thin-walled beam subjected to a transverse shear load, where does the shear flow $q$ vanish identically?
(A) At all free boundaries (edges)
(B) At the neutral axis
(C) At the shear center
(D) At the centroid
Answer Key:
A
Step-by-Step Verified Solution
### Solution: Because there are no external surface tractions acting on the free edges of an open thin-walled section, shear stress and shear flow $q = \tau t$ must be zero at all free boundaries. Correct: A.
