Answer
$$
\begin{aligned}
& F_R=0 \\
& M_{R o}=1.35 \mathrm{kip} \cdot \mathrm{ft}
\end{aligned}
$$
Work Step by Step
$$
\begin{array}{ll}
+\uparrow F_R=\Sigma F ; & F_R=0 \\
↺+M_{R O}=\Sigma M_O ; & M_{R O}=225(6)=1350 \mathrm{lb} \cdot \mathrm{ft}=1.35 \mathrm{kip} \cdot \mathrm{ft}
\end{array}
$$
