I am having some trouble with these questions

The assembly shown is welded to collarA that fits on the vertical pin shown. The pin can exert couples about the x and z axes but does not prevent motion about or along they axis. For the loading shown, determine the tension in each cable and the reaction at A. The frame ACD is supported by ball-and-socket joints at A and D and by a cable that passes through a ring at B and is attached to hooks at G and H. Knowing that the frame supports at\fUsing the method of joints, determine the force in each member of the truss shown. State whether each member is in tension (7) or compression (C).
