A purple beam is hinged to a wall to hold up a blue sign. The beam has a mass of mb = 6.7 kg and the sign has a mass of ms = 17.3 kg. The length of the beam is L = 2.81 m. The sign is attached at the very end of the beam, but the horizontal wire holding up the beam is attached 2/3 of the way to the end of the beam. The angle the wire makes with the beam is θ = 34.3°
What is the tension of the wire? The max mass sign that can be held without the wire breaking at T=940 N?
What is the net force the hinge exerts on the beam?
