The symmetry axis is usually associated with regional stress or gravity.

You only have to look at the diffraction pattern shown to see a nice 10-fold symmetry axis.

It possesses a 2-fold symmetry axis passing through the heteroring.

If multiple symmetry axes are present, they will necessarily intersect at a single point, and this is usually taken to be the center.

Proper support constraints are imposed with special attention paid to nodes on symmetry axes.

There are two orthogonal symmetry axes and so the motion is quadrupole.

Its symmetry axis is the same axis that goes through the nitrogen atom.

That is, for these kites the two equal angles on opposite sides of the symmetry axis are each 90 degrees.

For example, it is possible to define a symmetry axis in order to produce symmetrical low resolution meshes.

Arbitrary irradiation angles enforce an anisotropy along one specific symmetry axis.

Symmetry axis: an axis around which a rotation by results in a molecule that is nothing like the original at all.

However, the pentagons are not necessarily regular, so the structure normally has no fivefold symmetry axes.

In both cases e may again be identified as the eccentricity of the ellipse formed by the cross section through the symmetry axis.

They are geometrical symmetry axes, regardless of the mass distribution of the aircraft.

The Lagrange top is a symmetric top, in which the center of gravity lies on the symmetry axis.

It is convenient to choose as body-fixed z-axis the highest-order symmetry axis.

(The first three have a vertical symmetry axis, and the last two each have a different diagonal one.)

Channeling is observed when the incident beam is aligned with a major symmetry axis of the crystal.

For discrete symmetry with multiple symmetry axes through the same point, there are the following possibilities:

For example, the gnomon may be aligned with the celestial poles and located also along the symmetry axis of a cone or a cylinder.

Radial stress, a stress in directions coplanar with but perpendicular to the symmetry axis.

Vertical and horizontal stems refer to the symmetry axis and the basal plane respectively.

The two interior angles of a kite that are on opposite sides of the symmetry axis are equal.

The dinuclear ferroxidase centers are located at the interfaces between subunits related by 2-fold symmetry axes.

Thus, corresponding to our symmetry axis we have a timelike congruence made up of circles and corresponding to certain observers.
