A crow sits on a clothesline midway between two poles as shown. Each end of the rope makes an angle of θ = 28° below the horizontal where it connects to the pole. If the combined weight of the crow and the rope is 11.1 N, what is the tension in the rope?

sum vertical forces: PLeft+Poleright-11.1N=0
So, looking at the left pole, of the pole is holding upwards 11.1N/2, then tension=11.2/(2sin28)
