300 N 30° K 200 N 3. Three chains act on the bracket such that they create a resultant force having a magnitude of 500 N. 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 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. Force F acts in this direction. e. (USE GEOMETRIC METHOD ONLY) [4 marks]
