For example, are you asking about:
* The tail of an animal? In this case, I need to know what animal you are referring to. The strength of a tail varies greatly depending on the species and its purpose.
* A mechanical tail? I need to know more about the specific tail, like its material, design, and intended use.
* A metaphorical tail? Perhaps you are talking about the tail of a story or event?
Please give me more information so I can understand your question and give you a helpful answer.
