Three chains act on the bracket, producing a 600-lb force as a resultant. If two of the chains are subjected to known forces, as shown, Determine the third chain's angle theta, measured clockwise from the positive x axis, so that the magnitude of force F in this chain is a minimum. All forces lie in the x – y plane. What is the magnitude of F?
