A simple truss structure is subjected to three active forces and two supporting forces as shown in the figure. Set

$P_1=6kN,P_2=9kN,$ and $P_3=12kN.$

Sign convention: negative if external force is to the left or downward; negative if internal force is compressive.

Supporting force at $A$ in $x-$direction, $A_x=$

Supporting force at $A$ in $y-$direction, $A_y=$

Supporting force at $D$ in $x-$direction, $D_x=$

Supporting force at $D$ in $y-$direction, $D_y=$
