that is, the straight line joining the vertex and the
center of the base; the axis of a circle, any straight

6. (Fine Arts) The primary or secondary central line of any
Anticlinal axis (Geol.), a line or ridge from which the

Axis of a curve (Geom.), a straight line which bisects a
system of parallel chords of a curve; called a principal
axis, when cutting them at right angles, in which case it
divides the curve into two symmetrical portions, as in the
parabola, which has one such axis, the ellipse, which has
two, or the circle, which has an infinite number. The two
axes of the ellipse are the major axis and the minor
axis, and the two axes of the hyperbola are the
transverse axis and the conjugate axis.

center and perpendicular to its surfaces.
Axis of a telescope or microscope, the straight line with

intersecting each other, to which points are referred for
the purpose of determining their relative position: they
are either rectangular or oblique.
Axes of co["o]rdinates in space, the three straight lines
in which the co["o]rdinate planes intersect each other.
Axis of a balance, that line about which it turns.

through the center about which it vibrates, and
perpendicular to the plane of vibration.

prismatic rings or curves are arranged. --Brewster.
Axis of revolution (Descriptive Geom.), a straight line
about which some line or plane is revolved, so that the
several points of the line or plane shall describe circles
with their centers in the fixed line, and their planes
perpendicular to it, the line describing a surface of
revolution, and the plane a solid of revolution.
Axis of symmetry (Geom.), any line in a plane figure which
divides the figure into two such parts that one part, when
folded over along the axis, shall coincide with the other

considered with reference to the sphere on which it lies),
the diameter of the sphere which is perpendicular to the
plane of the circle. --Hutton.

horizontal elastic forces of tension and compression,
exerted by the fibers in any cross section of a girder.

transmitted light suffers no double refraction. All
crystals, not of the isometric system, are either uniaxial
Optic axis, Visual axis (Opt.), the straight line passing
through the center of the pupil, and perpendicular to the
surface of the eye.
Radical axis of two circles (Geom.), the straight line
perpendicular to the line joining their centers and such
that the tangents from any point of it to the two circles
shall be equal to each other.
Spiral axis (Arch.), the axis of a twisted column drawn
spirally in order to trace the circumvolutions without.
