Axis vs. Hinge

A straight line about which a body or geometric object rotates or may be conceived to rotate.

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: all other translations or rotations being prevented, and thus a hinge has one degree of freedom.

An unlimited line, half-line, or line segment serving to orient a space or a geometric object, especially a line about which the object is symmetric.

A jointed or flexible device that allows the turning or pivoting of a part, such as a door or lid, on a stationary frame.

A reference line from which distances or angles are measured in a coordinate system.

A similar structure or part, such as one that enables the valves of a bivalve mollusk to open and close.

A center line to which parts of a structure or body may be referred.

A small folded paper rectangle gummed on one side, used especially to fasten stamps in an album.

An imaginary line to which elements of a work of art, such as a picture, are referred for measurement or symmetry.

A point or circumstance on which subsequent events depend.

(mathematics) A fixed one-dimensional figure, such as a line or arc, with an origin and orientation and such that its points are in one-to-one correspondence with a set of numbers; an axis forms part of the basis of a space or is used to position and locate data in a graph (a coordinate axis)
