A cantilever beam having a rectangular cross-section of width $60 \mathrm{~mm}$ and depth $100 \mathrm{~mm}$, is made of aluminum alloy. The material mechanical properties are: Young's modulus, $\mathrm{E}=73 \mathrm{GPa}$ and ultimate stress, $\sigma_{u}=480 \mathrm{MPa}$. Assuming a factor of safety of $4,$ the maximum bending moment (in $\mathrm{kN}-\mathrm{m}$ ) that can be applied on the beam is_________________(accurate to one decimal place).
