If the direction of the resultant force acting on the eyebolt is defined by the unit vector uFr= cos30j +sin 30k, determine the coordinate direction angles of F3 and the magnitude of Fr.
F1=700lb and is 30 degrees from x axis
F2=600lb in yz plane and defined by triangle with hypot=5, opposite=3 and adj=4
F3=800lb in yz plane closer to z axis.
