Two forces $P$ and $Q$ pass through a point $A$ which is 4 m to the right of and 3 m above a moment center $O$. Force $P$ is 890 N directed up to the right at 30° with the horizontal and force $Q$ is 445 N directed up to the left at 60° with the horizontal.
Draw a sketch of the situation and determine the moment of the resultant of these two forces about point $O$.
$M_O = 1676.74 \, \text{ N}\cdot\text{m}$ (counterclockwise).
