==Description==
A '''hinge''' is a type of bearing that connects two solid objects, typically allowing only a limited [[angle]] of [[rotation]] between them. Two objects [[connected]] by an [[ideal]] hinge rotate relative to each other about a fixed [[axis]] of rotation. Hinges may be made of [[flexible]] material or of moving components. In [[biology]], many joints function as hinges.
Since at least [http://en.wikipedia.org/wiki/Medieval medieval] times there have been hinges to [http://en.wikipedia.org/wiki/Draw_bridge draw bridges] for defensive purposes for [[fortified]] buildings. Hinges are used in contemporary [[architecture]] where building settlement can be [[expected]] over the life of the building. For example, the [http://en.wikipedia.org/wiki/Dakin_Building Dakin Building], California was designed with its entrance ramp on a large hinge to allow settlement of the building built on piles over bay mud. This device has been effective.
Hinges appear in large [[structures]] such as elevated freeway and railroad viaducts. These are included to reduce or eliminate the [[transfer]] of bending [[stresses]] between structural components, typically in an effort to reduce [[sensitivity]] to earthquakes. The primary reason for using a hinge, rather than a simpler device such as a slide, is to prevent the [[separation]] of adjacent components. When no bending stresses are [[transmitted]] across the hinge it is called a ''zero moment hinge''.[http://en.wikipedia.org/wiki/Hinge]
