# Hanged bird feeder

Classical Mechanics Level 2

The above diagram shows a bird feeder hanging from the ceiling by three wires $$A, B$$ and $$C.$$ Wires $$A$$ and $$B$$ form angles of $$60^{\circ}$$ and $$30^{\circ},$$ respectively, with the ceiling. Wire $$C$$ is hanging from the intersection of $$A$$ and $$B,$$ and is connected to the top of the bird feeder. If the weight of the feeder is $$65 \text{ N} ,$$ what is the tension force on the wire $$B?$$
