A purple beam is hinged to a wall to hold up a blue sign. The beam has a mass of mb = 6.8 kg and the sign has a mass ofms = 17.6 kg. The length of the beam is L = 2.88 m. The sign is attached at the very end of the beam, but the horizontalwire 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 = 30.2°.

1)What is the tension in the wire?
2) What is the net force the hinge exerts on the beam?
3)The maximum tension the wire can have without breaking is T = 1003 N.
What is the maximum mass sign that can be hung from the beam?
