👉 Crumbling refers to a state of disintegration, collapse, or failure. It describes a physical condition where an object is no longer in its original shape and size, but instead has become smaller, lighter, or less dense than it was originally. In physics, crumbling can be explained through the concept of the elastic limit. In a material subjected to stress, if the strain exceeds the elastic limit (which occurs when the material reaches its maximum yield strength), then the material breaks down and becomes
