(5) If the beam is made of material having an allowable tensile and compressive stress of \( \left(\sigma_{\text {allow }}\right)_{t}=75 \mathrm{MPa} \) and \( \left(\sigma_{\text {allow }}\right)_{c}=150 \mathrm{MPa} \), respectively, determine the maximum magnitude of moment, \( \boldsymbol{M} \). (6) If the beam is made from wood having an allowable shear stress \( T_{\text {allow }}= \) \( 3 \mathrm{MPa} \), determine the maximum magnitude of \( \mathbf{P} \).
