The low strength concrete floor slab is integrated with a wideflange A-36 steel beam using shear studs(not shown) to form the composite beam as shown in figure 1 . If the allowable bending stress for the concrete is \( \left(\sigma_{\text {conc }}\right) \) allow \( =10 \mathrm{MPa} \), and allowable bending stress for steel is \( \left(\sigma_{\text {st }}\right)_{\text {allow }}=165 \mathrm{MPa} \), determine the maximum allowable internal moment \( \mathbf{M} \) that can be applied to the beam. Take \( E_{c o n c}=26.5 \mathrm{GPa} \).
