Hinge

The pivot point of a door, gate, or lid is called a hinge, which allows it to swing open and shut smoothly, providing easy access and convenient movement. A hinge is a crucial component that connects two parts, enabling them to rotate freely around a central axis. By facilitating smooth motion, hinges make it possible for people to open doors, gates, and other objects with minimal effort. This versatility makes hinges an essential feature in many architectural and engineering designs.
