MCQ · 1 Mark
Aerospace Structures • Thin-Walled Structures • Shear Center of Open Thin-Walled Sections
For a thin-walled channel section (C-channel) with horizontal flanges and a vertical web, the shear center lies:
(A) Outside the section, on the symmetry axis opposite the web
(B) Exactly at the centroid of the section
(C) At the midpoint of the vertical web
(D) At the tip of the upper flange
Answer Key:
A
Step-by-Step Verified Solution
### Solution: In a C-channel, flange shear flows produce a net couple that places the shear center outside the web on the side opposite the flanges. Correct: A.
