Consider a simply supported beam $\text{PQ}$ as shown in the figure. A truck having $100$ $\text{kN}$ on the front axle and $200$ $\text{kN}$ on the rear axle, moves from left to right. The spacing between the axles is $3\: m$. The maximum bending moment at point $R$ is _______________ $\text{kNm}$ (in integer)
