For the bracket shown with the forces $P=910N$ and $Q=-910N$ and distances $a=29m$ and $b=1\mathrm{.}2m$ determin the moment about

point $D$ due to the force $P$ and the moment about rod $CD$ due to the force $P.$

Moment about point $D,M_D=$

$j+$

k $N^{*}m$

Moment about rod $CD,M_{CD}=$

$N^{*}m$

$($Click to select$)$

as viewed from $C$ towards $D.$ Note: $Q$ is parallel to $CD.$
