Three chains act on the bracket such that they create a resultant force having a magnitude of 600 lb . If two of the chains are subjected to known forces, as shown,
(Figure 1) determine the angle 0 of the third chain measured clockwise from the positive z axis, so that the magnitude of force F in this chain is a minimum. All forces
lie in the r-y plane. Hint. First find the resultant of the two known forces. Force F acts in this direction.
Express your answer with the appropriate units.
