The $4$ KN load is hoisted at a constant speed using motor $\backslash ($ M $\backslash ),$ which has a weight of $0\mathrm{.}45$ KN $.$ Determine the resultant internal loadings acting on the cross$-$section through points $\backslash ($ B $\backslash )$ and $\backslash ($ C $\backslash )$ in the beam. The beam has a weight of $\backslash (0\mathrm{.}6\backslash$mathrm$\{$KN$\}/\backslash$mathrm$\{$m$\}\backslash )$ and is fixed to the wall at $\backslash ($ A $\backslash ).$ The radius of the pulley where the load is hoisted $\backslash (=0\mathrm{.}075\backslash$mathrm$\{$~m$\}\backslash ).$
