The ring of negligible size is subjected to a vertical force of 200 lb. Determine the required length / of rd AC such that the tension acting in AC is 160 lb. Also, what is the force in cord AB? Hint: Use the equilibrium condition to determine the required angle θ for attachment, then determine / using trigonometry applied to triangle ABC.
