고체역학 (Beer) — Shearing Stresses in Beams: Problem 6.71

6.69 through 6.74 Determine the location of the shear center \(O\) of a thin-walled beam of uniform thickness having the cross section shown. For Figure P6.71: The cross section is a thin-walled channel-like shape with inclined flanges. Top flange \(AB\) and bottom flange \(DE\) both have a horizontal projection of 4 in. and a vertical projection of 3 in. The vertical web \(BD\) has a height of 5 in. The thickness \(t\) is uniform throughout the section.
