A purple beam is hinged to a wall to hold up a blue sign. The beam has a mass of mb = 6.1 kg and the sign has a mass of ms = 16.6 kg. The length of the beam is L = 2.87 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 ? = 31.8°.
What is the tension in the wire?
What is the net force the hinge exerts on the beam?
The maximum tension the wire can have without breaking is T = 970 N.
What is the maximum mass sign that can be hung from the beam?
