Two cables which have known tension are attached to the top of pylon [i]AB[/i]. A third cable [i]AC[/i] is used as a guy wire. Determine the tension in cable [i]AC[/i] knowing that the resultant of the forces exerted at [i]A[/i] by the three cables must be vertical.[br][br]Adjust the tension in the guy wire to make the resultant of the three forces vertical.
