virtual    : [v'ɚtʃuəl]
Virtual \Vir"tu*al\ (?; 135), a. [Cf. F. virtuel. See {Virtue}.]
1. Having the power of acting or of invisible efficacy
without the agency of the material or sensible part;
potential; energizing.
[1913 Webster]

Heat and cold have a virtual transition, without
communication of substance. --Bacon.
[1913 Webster]

Every kind that lives,
Fomented by his virtual power, and warmed. --Milton.
[1913 Webster]

2. Being in essence or effect, not in fact; as, the virtual
presence of a man in his agent or substitute.
[1913 Webster]

A thing has a virtual existence when it has all the
conditions necessary to its actual existence.
--Fleming.
[1913 Webster]

To mask by slight differences in the manners a
virtual identity in the substance. --De Quincey.
[1913 Webster]

{Principle of virtual velocities} (Mech.), the law that when
several forces are in equilibrium, the algebraic sum of
their virtual moments is equal to zero.

{Virtual focus} (Opt.), the point from which rays, having
been rendered divergent by reflection of refraction,
appear to issue; the point at which converging rays would
meet if not reflected or refracted before they reach it.

{Virtual image}. (Optics) See under {Image}.

{Virtual moment} (of a force) (Mech.), the product of the
intensity of the force multiplied by the virtual velocity
of its point of application; -- sometimes called {virtual
work}.

{Virtual velocity} (Mech.), a minute hypothetical
displacement, assumed in analysis to facilitate the
investigation of statical problems. With respect to any
given force of a number of forces holding a material
system in equilibrium, it is the projection, upon the
direction of the force, of a line joining its point of
application with a new position of that point indefinitely
near to the first, to which the point is conceived to have
been moved, without disturbing the equilibrium of the
system, or the connections of its parts with each other.
Strictly speaking, it is not a velocity but a length.

{Virtual work}. (Mech.) See {Virtual moment}, above.
[1913 Webster]

virtual
adj 1: being actually such in almost every respect; "a practical
failure"; "the once elegant temple lay in virtual ruin"
[synonym: {virtual(a)}, {practical(a)}]
2: existing in essence or effect though not in actual fact; "a
virtual dependence on charity"; "a virtual revolution";
"virtual reality"
