3. Refer to the shaft-and-bracket assembly in Figure 3.
(a) Determine the force and the couple-moment at O that together form a force-couple system at O that is statically equivalent to the two forces applied as shown. (The 800-N force is directed 45 degrees below the horizontal plane; and the 600-N force is directed 30 degrees above the horizontal plane.) Report your answers in Cartesian form.
(b) Determine the magnitude of the shear force in the shaft at point O.
