Axis vs. Hinge — What's the Difference?

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.

The second cervical vertebra on which the head turns.

To attach by or equip with or as if with hinges or a hinge.

Any of various central structures, such as the spinal column, or standard abstract lines used as a positional referent.

To consider or make (something) dependent on something else; predicate

(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)

The breaking off of the distal end of a knapped stone flake whose presumed course across the face of the stone core was truncated prematurely, leaving not a feathered distal end but instead the scar of a nearly perpendicular break.

(botany) The main stem or central part about which organs or plant parts such as branches are arranged

(obsolete) To bend.

(military) An alliance or coalition.

To move or already be positioned in such a fashion that it presents itself as rotation when an off-centre fixed point is taken into account.
