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 of ms =
17.6 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 ? = 30.1Â°. 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 = 1002.0 N.What is the maximum mass
sign that can be hung from the beam?
