고체역학 (Gere) — Stresses in Beams (Basic Topics): Problem 5.6-1

5.6-1 A simply supported wood beam having a span length \(L = 3.6\) m is subjected to unsymmetrical point loads, as shown in the figure. Select a suitable size for the beam from the table in Appendix G. The allowable bending stress is \(12\) MPa and the wood weighs \(5.5\) kN/m\(^3\).
