A $3\mathrm{.}150-$kip force $P$ is applied at point $D$ of the cast$-$iron post shown. Replace that force with an equivalent force$-$couple system at the center $A$ of the base section. $($Include a minus sign if necessary.$)$

The equivalent force is $$ kips$)$j $+]$ kips$)$k$.($Round the final answers to three decimal places.$)$

The equivalent couple is $$

kip.in$..i+1$

kip.in$.$
