A store's sign has a mass of 20 kg and is 3.0 m long. It is uniform, so its center of gravity is at the center of the sign. It is supported by a bolt attached to the wall at one end and by a wire at the other end, as shown in the figure. What is the tension in the wire? 3.0 m Hint: A static equilibrium problem. Set the net force in both directions and the net torque equal to zero. It will be convenient to take the bolt as the rotation axis. O 120 N O 180 N O 300 N O 230 N
