Three cables are pulling on a ring located at the origin, as shown in the diagram below. FA is 200 N in magnitude with a transverse angle of 30° and an azimuth angle of 140°. FB is 240 N in magnitude with coordinate direction angles α = 135° and β = 45°. Determine the magnitude and direction of FC so that the resultant of all 3 force vectors lies on the z-axis and has a magnitude of 300 N. Specify the direction of FC using its coordinate direction angles.
