Problem -2: a store sign is supported by the pole shown in the figure. The sign wight is 200 lb. wind force is 500 lb. and is acting perpendicular to the sign (i.e. in y-direction) Determine the magnitude and direction of the reaction force and moment at point A (Fx, Fy, Fz, Mx, My, Mz) Hint: You can use the 3D notation and vector analysis for forces and moments.
