고체역학 (Gere) — Stresses in Beams (Advanced Topics): Problem 6.9-2

6.9-2 Calculate the distance \( e \) from the centerline of the web of a UPN 100 channel section to the shear center \( S \) (see figure). Note: For purposes of analysis, consider the flanges to be rectangles with thickness \( t_f \) equal to the average flange thickness given in Table F-3 in Appendix F.
