Structure OABC is built in at point O and supports forces from two cables. Cable EAD passes through a frictionless ring at point A$,$ and cable OCG passes through a frictionless ring at point C$.$ The force in cable EAD is $800$ lb and the force in cable OCG is $480$ lb$.$

The vertical section OAB of the structure along the vertical z$-$axis is perpendicular to the horizontal xy plane.The horizontal section BC is parallel to the y$-$axis. Point O is at the origin of the x$,$ y$,$ and z axes. Point A on the vertical section of the structure is at a distance of $6$ feet from the origin. Point B at the top end of the vertical section of the structure is at a distance of $6$ feet from point A$.$ Point C at the end of the horizontal section is at a distance of $9$ feet from point B$.$ Point D on the y$-$axis is at a distance of $8$ feet from the origin. Point E on the x$-$axis is at a distance of $8$ feet from the origin. Point G on the x$-$axis is at a distance of $12$ feet from point E$.$ A cable from point E passes through the ring at point A and is connected to point D$.$ A cable from point G passes through the ring at point C and is connected to point O$.$
