A beam has a symmetrical cross section (Figure P8.27). A vertical web with a thickness of 0.60 mm is welded to two 20 mm by 20 mm by 4 mm angle-section (A = 146 mm2 and centroid location 6.4 mm) stringers. The two horizontal webs have a thickness of 0.60 mm•and are welded to the angle sections and 20 mm by 20 mm by 4 mm T-section stringers. Locate the shear center for the cross section.
