Cable AB exerts a force of 1300-lb at point A that is directed along the line from A to B. The cable AC exerts a force of 750-lb at point A that is directed along the line from A to C. Determine the magnitude of the total force exerted at point A by the two cables. Determine the moment of this total force about point C. Determine the moment of this total force about point B. .
