The figure below shows a bird feeder that weighs 190.5 N. The feeder is supported by a vertical cable, which is in turn tied to two cables, each of which is attached to a horizontal post. The left cable makes a 60° angle with the post, while the right cable makes a 30° angle. What is the tension in each cable (in N)? 60° 30

The figure below shows a bird feeder that weighs 190.5 N. The feeder is supported by a vertical cable, which is in turn tied to two cables, each of which is attached to a horizontal post. The left cable makes a 60° angle with the post, while the right cable makes a 30° angle. What is the tension in each cable (in N)? 60° 300 Bird food left cable 190.5 It appears you used 30.09 for both angles. Note the left cable makes a 60.09 angle with the post, while the right cable makes a 30.09 angle. N right 85 35 cable Consider first the system of just the feeder What forces act on it? What is the tension in the bettom cable? Next consider the point where the three cables meet. What are the force components in the x-direction? The y-direction?
