A purple beam is hinged to a wall to hold up a blue sign. The beam has a mass of mb = 6 kg and the sign has a mass of ms = 16.1 kg. The length of the beam is L = 2.74 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 = 30°.
