The term "hinged" refers to an object that is attached to another object in a way that allows it to pivot or swing open and closed. This mechanism is commonly found in doors, gates, and lids, enabling them to move freely while remaining connected. Hinges can be made from various materials, including metal and plastic, and come in different designs to suit specific needs. In engineering and design, hinged structures are essential for functionality and accessibility. For example, a door uses hinges to allow entry and exit, while a lid on a box can be opened to access its contents. Hinged designs are crucial in many everyday items, enhancing convenience and usability.
