Determine the x, y, z components of reaction at the fixed wall A. The 150-N force is parallel to the z axis and the 200-N force is parallel to the y axis.
\Sigma F_x=0 ; \quad A_x=0
\Sigma F_y=0 ; \quad A_y+200=0
A_y=-200 \mathrm{~N}
\Sigma F_z=0 ; \quad A_z-150=0A_z=150 \mathrm{~N}
\Sigma M_x=0 ; \quad-150(2)+200(2)-\left(M_A\right)_x=0\left(M_A\right)_x=100 \mathrm{~N} \cdot \mathrm{m}
\Sigma M_y=0 ; \quad\left(M_A\right)_y=0\Sigma M_z=0 ; \quad 200(2.5)-\left(M_A\right)_z=0
\left(M_A\right)_z=500 \mathrm{~N} \cdot \mathrm{m}
