Interlocking refers to a method where two or more components fit together in a way that they cannot easily be separated. This technique is commonly used in various fields, such as construction, where bricks or tiles are designed to interlock for stability and strength. It ensures that the pieces work together seamlessly, enhancing the overall integrity of the structure. In nature, interlocking can be observed in the way certain animals, like geese, form a V-formation during flight. This formation allows them to conserve energy and maintain a cohesive group. The interlocking of their wings helps to create an aerodynamic advantage, demonstrating how this concept can be applied in both human-made and natural systems.
