A wall bracket is subjected to external forces, as shown in the figure $($if the im does not load, click here darr to download it$).$ The lengths of different sections the bracket are: $OA=2m,AB=5\mathrm{.}93m,BC=3\mathrm{.}65m,CD=9\mathrm{.}24m$ and $DE=3\mathrm{.}95m.$ The self$-$weight and the width of the bracket can be ignored. Calculat the moment $($in $kN-$m unit$)$ at point $O,$ assuming that the force at $C$ is applied horizontally and that the force at $E$ is applied vertically. Note that members A and $CD$ are parallel.

Please enter the moment calculated to $2$ decimal places and specify the positi or negative value of the moment in your answer. Take care to correctly accoun for the proper sign convention for the direction

of moments $($counterclockwise positive$).$
