고체역학 (Gere) — Stresses in Beams (Basic Topics): Problem 5.11-3

5.11-3 A welded steel girder having the cross section shown in the figure is fabricated of two \(450\text{ mm} \times 24\text{ mm}\) flange plates and a \(1.6\text{ m} \times 10\text{ mm}\) web plate. The plates are joined by four longitudinal fillet welds that run continuously throughout the length of the girder. If the girder is subjected to a shear force of \(1300\text{ kN}\), what force \(F\) (per meter of length of weld) must be resisted by each weld?
