Question
1. Three chains act on the bracket such that they create a resultant force having a magnitude of 490 lb. If two of the chains are subjected to known forces, as shown, determine the orientation ? 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. Forces F acts in this direction. **The most important part is please explain what you do !! I have got the resultant force of the 200 and 300 lb forces to be 264.57 lb and the angle it makes is 10.8 degrees clock wise from the positive x-axis I am not sure what the question is technically asking.Explanation / Answer
