Three cables pull on the pipe such that they create a resultant force having a magnitude of 900 lb. if two of the cables are subjected to known forces, determine the angle θ of the third cable so that the magnitude of force f in this cable is a minimum. all forces lie in the x–y plane. what is the magnitude of f?
