A boat trailer is subjected to the forces shown where the forces at points A-E are vertical and the forces at points F and G lie in the yz plane. Determine

(a) an equivalent force system at point O.

(b) an equivalent force system consisting of a single force, specifying the x and y coordinates of the point where the force’s line of action intersects the xz plane.
