 Consider a very thin wire that is one atom thick. In this case, you can observe what happens to each bond in the wire when a heavy ball is attached to the end of the wire (Figure to the left). **In this case, each bond is "stretched" by roughly the same amount. This is the model to consider when you think "the tension is the same throughout the wire."** Consider a very thin wire that is one atom thick.
