Definition: The term "rathole" is a technical term in physics that refers to a point where a string or rod can be bent without changing its length. In other words, it's a point at which a physical system can maintain its shape under certain conditions while being able to change its length. Ratholes are often used in the context of elasticity and solid mechanics to describe the behavior of materials that can deform without breaking. They can also be found in many engineering applications such as in bridges,
