A purple beam is hinged to a wall to hold up a blue sign. The
beam has a mass of mb = 6.3 kg and the sign has a mass
of ms = 15.1 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 =
31.7°.
A)What is the tension in the wire?
B)What is the net force the hinge exerts on the beam?
C)The maximum tension the wire can have without breaking is T = 931
N.
What is the maximum mass sign that can be hung from the beam?
