A weight $W$ is hung from ring $A,$ and cable BAC runs through the ring, connecting to fixed supports at $B$ and $C($Note: The magnitude of tension is the same in both segments of cable BAC$).$ To maintain static equilibrium, forces $P$ acting along the $x-$axis and $Q$ acting along the $z-$axis are applied to the ring. Given $W=1200N,$ find the magnitudes of $P$ and $Q.$ Please draw a clear free body diagram illustrating all forces and their respective directions.
