Draw the FBD of pt. A. Write out the forces FAB, FAC, and FAD in vector form. Set up the three equations of equilibrium. Then determine the tension force in cables AB and AC that would be required to hold the 120-lb crate in equilibrium in the position shown in the figure if the magnitude of FAD is 175.8 lb.
