Question:
The simply supported beam is composed of two W12 \(\times 22\) sections built up as shown. Determine if the beam will safely support a loading of \(w=2 \mathrm{kip} / \mathrm{ft}\). The allowable bending stress is \(\sigma_{\text {allow }}=22 \mathrm{ksi}\) and the allowable shear stress is \(\tau_{\text {allow }}=14\) ksi.
