The bearings at \( A \) and \( B \) exert only vertical reactions on the shaft. Take \( \mathbf{d}_{1}=0.1 \mathrm{~m}, \mathbf{d}_{\mathbf{2}}=0.3 \mathrm{~m}, \mathbf{d}_{\mathbf{3}}=0.3 \mathrm{~m}, \mathbf{d}_{\mathbf{4}}=0.2 \) \( \mathrm{m}, \mathrm{F}_{1}=567 \mathrm{~N}, \mathrm{~F}_{2}=388 \mathrm{~N} \), and \( \mathrm{F}_{3}=195 \mathrm{~N} \). Draw the shear and moment diagrams for the shaft if it is subjected to the vertical loadings and determine the maximum bending moment in \( \mathbf{N}-\mathbf{m} \). Be mindful of the sign convention.
