The beam with a circular hole shown in is made of material having an allowable tensile and compressive stress of \( \left(\sigma_{\text {allow }}\right)_{t}=187 \mathrm{MPa} \) and \( \left(\sigma_{\text {allow }}\right)_{c}=165 \mathrm{MPa} \), respectively. The beam with a circular hole shown in is made of material having an allowable tensile and compressive stress of \( \left(\sigma_{\text {allow }}\right)_{t}=187 \mathrm{MPa} \) and \( \left(\sigma_{\text {allow }}\right)_{c}=165 \mathrm{MPa} \), respectively. Determine the maximum allowable magnitude of the internal moment \( \mathbf{M} \) that can be applied to the beam. Express your answer to three significant figures and include appropriate units.
