[2] It has the hinge that characterizes all tortoises in the genus Kinixys. There are no recognized subspecies.
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.
A revolute joint (also called pin joint or hinge joint) is a one-degree-of-freedom kinematic pair used frequently in mechanisms and machines. [1] The joint constrains the motion of two bodies to pure rotation along a common axis. The joint does not allow translation, or sliding linear motion, a constraint not shown in the diagram. Almost all ...
The forest hinge-back tortoise (Kinixys erosa), also known commonly as the serrated hinge-back tortoise or Schweigger's tortoise, is a species of tortoise in the family Testudinidae. The species is indigenous to the tropical forests and marshes of central and western Africa .
The dihedral synchro-helix actuation door system is a type of door with a hinge mechanism which allows the doors to rotate 90° by sweeping outwards and upwards at the hinge. [1] It was designed and developed by Christian von Koenigsegg on behalf of high-performance sports cars manufacturer, Koenigsegg Automotive AB . [ 2 ]

A typical 90-degree bellcrank consists of an L-shaped crank pivoted where the two arms of the L meet. Moving rods or cables are attached to the outer ends of the L. When one is pulled, the L rotates around the pivot point, pulling on the other rod. A typical 180-degree bellcrank consists of a straight bar that pivots at or near its center.
Similar to the Geodreieck, a number of other protractor triangle types exist for navigation purposes. Various designs are named navigation (protractor) triangle, nautical navigational triangle, nautical set square, Portland (navigational) triangle or Portland protractor triangle, Kent-type triangle, Inoue-type A/B nautical triangle or plotting triangle, course triangle, yachtsmen triangle, and ...
