Rotational Axis
Rotational axis is an imaginary line which acts an axis and is drawn on a crystal. By rotating the crystal along the axis, it is possible to repeat a crystal face.

There are 7 possible forms which may be present in the Dihexagonal Dipyramidal class: ...
The reflection, rotation, inversion, and rotoinversion symmetry operations may be combined in a variety of different ways. There are thirty-two possible unique combinations of symmetry operations.
For such a rigid rotation, there is no change in the relative positions of the fluid elements, and so there is no viscous force associated with this term. The remaining symmetric term is responsible for the viscous forces in the fluid.
Axis Of SymmetryAn axis of symmetry (also called a rotational axis) is an imaginary line around which an object can be rotated a certain number of degrees and look like the original shape.
The cycle of alternate rising and falling of the surface of an ocean or large lake, caused by the gravitational pull of the Sun and especially Moon in interaction with the Earth's rotation.
Axis of Symmetry: Also known as the rotational axis. It is when an imaginary line passes through an object in such a way that part of the figure on one side of the line is a mirror image of the part on the other side of the line.
Axis Of Symmetry: (also called a rotational axis). An imaginary line around which an object can be rotated a certain number of degrees and still resemble the original shape.
An axis of symmetry (also called a rotational axis) is an imaginary line around which an object can be rotated a certain number of degrees and look like the original shape.
It requires specialized equipment, capable of greater rotational speed of the cutting wheel and greater pressure on the gem than does equipment used to cut colored stones.
Moving watch part, usually circular, oscillating about its axis of rotation. The hairspring coupled to it makes it swing to and fro, dividing time into exactly equal parts. Each of the to-and-fro movements of the balance is called an oscillation.
Moving part of a watch, usually circular, oscillating about its axis of rotation. The vibrations of the balance, governed by its spring, perform the actual timekeeping indicated by the hands on the dial.

Sphenoids are found in monoclinic and orthorhombic minerals, and have two-fold rotational axes.
Tumbling barrels are often hexagonal in outline in order to enhance the stirring action of barrel rotation.

In effect, each band of glowing color represents a different crack that opened and was filled. Each band contains a new orientation of embedded crocidolite fibers that record minute rotations of the rock as it formed.
The reproducibility of such a photograph is guaranteed, as the angle to the table-culet axis, at which he diamond is brought in front of the laser beam, is not important. It can be taken as certain that each picture taken during rotation around the ...
And speaking of great lengths, we even offer hard-to-find 8-inch and 9-inch diamond tennis bracelets. With a steady rotation of specials on diamond bracelets, you can even pick up a cheap diamond tennis bracelet at the last minute! ...
The latter wears away the diamond, producing a flat facet. The lap is kept moistened with oil and from time to time fresh oil and diamond dust are applied. A speed of about 2,000 rotations per minute is used.
