The floor of an airplane cargo bay is shown in a horizontal position.

(a) Determine an equivalent force system at point O.

(b) Determine an equivalent force system consisting of a single force, and specify the x and z coordinates of the point where the force’s line of action intersects the floor.

(c) Keeping points A-D at the locations shown, suggest a repositioning of the forces so that the location of the force system described in Part (b) is closer to point O.
