A laser cut plywood box with two living hinges. A variant on the kerf bend can be used to create living hinges in laser cut wood. The technique is popular for making light-duty hinges with large radii. [7] It is also possible to create a living wood joint by hand, but the result is less accurate. [8]
Diagram of a structure featuring plastic hinges. In the structural engineering beam theory, plastic hinge is the deformation of a section of a beam where plastic bending occurs. [1] In earthquake engineering plastic hinge is also a type of energy damping device allowing plastic rotation [deformation] of an otherwise rigid column connection. [2]
An ornate brass door hinge A barrel hinge. A hinge is a mechanical 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, with all other translations or rotations prevented; thus a hinge has one degree of freedom.
The name is derived from fish, [1] a wooden reinforcement of a "built-up" ship's mast that helped round out its desired profile. [2] The top and bottom faces taper inwards along their short dimensions to create an even alignment between the two rails when the fish plate is wedged into place by tightening its bolts during installation.

The hingemouth (Phractolaemus ansorgii) is a small freshwater fish that is found only in west central Africa, the sole member of the family Phractolaemidae of the family Kneriidae. The mouth can extend like a small trunk, thus the name, and has just two teeth, both in the lower jaw. Its mouth can extend up to 30% of the hingemouth's head length.
Also in 2019, the company started Hinge Labs to research successful matches and fine-tune the app's compatibility algorithm and other features. [19] Hinge was featured on CNET as one of the best dating sites for 2021. [20] A voice message feature was added to the app in October 2021. [21] As of 2023, Hinge had 23 million regular users. [22]
The hinge theorem holds in Euclidean spaces and more generally in simply connected non-positively curved space forms.. It can be also extended from plane Euclidean geometry to higher dimension Euclidean spaces (e.g., to tetrahedra and more generally to simplices), as has been done for orthocentric tetrahedra (i.e., tetrahedra in which altitudes are concurrent) [2] and more generally for ...
