A long uniformly distributed load of $10 \mathrm{kN} / \mathrm{m}$ and a concentrated load of $60 \mathrm{kN}$ are moving together on the beam ABCD shown in the figure (not drawn to scale). The relative positions of the two loads are not fixed. The maximum shear force (in $k N,$ round off to the nearest integer) caused at the internal hinge $\mathrm{B}$ due to the two loads is
