Friends:
I have been wondering how a conductor's tension is affected by birds landing on it and then flying away. By itself, the conductor has some tension obviously due to its weight. When a bird lands on the conductor, the tension increases. But what about when the bird flies away? By flapping its wings prior to takeoff, the bird will cause the conductor's tension to increase. But when the bird actually flies away (and let's say its a fat bird or there are a lot of birds) and the conductor sort of bounces up and down, does the conductor tension ever go to zero or become negative??
I appreciate any help! Thanks!
