The allowable bearing stress for the plates under the Part A supports at \( A \) and \( B \) shown in (Figure 1 ) is \( \left(\sigma_{b}\right)_{\text {allow }}=2.1 \mathrm{MPa} \). The plates \( A^{\prime} \) and \( B^{\prime} \) have square Determine the maximum load \( P \) that can be applied to the beam. cross sections of \( 200 \mathrm{~mm} \times 200 \mathrm{~mm} \) and \( 300 \mathrm{~mm} \times 300 \mathrm{~mm} \), respectively.
