Three chains act on the bracket such that they create a resultant force having a magnitude of 500 lb. If two of the chains are subjected to known forces, as shown, determine the angle of the third chain measured clockwise from the positive x axis, so that the magnitude of the force F in this chain is a minimum. All forces lie in the x-y plane. What is the magnitude of F? Hint: First find the resultant of the two known forces. Forces F acts in this direction.

Three chains act on the bracket such that they create a resultant force having a magnitude of 500 lb. If
two of the chains are subjected to known forces, as shown, determine the angle of the third chain
measured clockwise from the positive x axis, so that the magnitude of the force F in this chain is a
minimum. All forces lie in the x-y plane. What is the magnitude of F? Hint: First find the resultant of the
two known forces. Forces F acts in this direction.
