Physics

A purple beam is hinged to a wall to hold up a blue sign. Thebeam has a mass of mb = 6.7 kg and the sign has a mass of ms = 17.4kg. The length of the beam is L = 2.83 m. The sign is attached atthe very end of the beam, but the horizontal wire holding up thebeam is attached 2/3 of the way to the end of the beam. The anglethe wire makes with the beam is θ = 34.5°.

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 =946 N. What is the maximum mass sign that can be hung from thebeam?
