A steel cable is used to keep a 2.0 m long 10-kg bar horizontal. One end of the bar is attached to a hinged mount attached to a wall. The other end is connected to a cable that makes a 30° angle with the bar and attaches to the wall at a point directly above the hinged mount. A 20-kg, 60 cm long sign is then hung from the end of the bar, attached at points 5.0 cm in on each end of the sign, with one of the cables aligned with the end of the bar. What is the tension in the cable?
