The dimensions of the shap~ are shown in Fig. P8.22b. Consider the entire 18-ft length of the L = 20 ft supports a unifonnly distributed load ofw = 800 Ib/ft. The al- , lowable bending stress of the wood is 1,400 psi. If the aspect ratio of beam and determine: the solid rectangular wood beam is specified as h/b = 1.5 (Fig. (a) the maximum tension bending stress at any location along the P8.33b), determine theminimum width b that can be used for the beam. beam, and (b) the maximum compression bending stress at any location w along the beam.
