Press the button to change the pattern of vibration.

Also, selecting a vibration mode of the different vibrations that form the composite vibration enables the two rotors (A, B) to be rotated in the same direction or in the opposite directions.

The eigenfrequency of the main structure was designed to comply with the wind vibration mode of the American standards.

Similarily, it is the different modes of vibration of the strings that confer particular characteristics to particules, i.e. their mass and their charge.

The plug has a a vibration mode in case a traditional plug is not enough for you.

Vibrations by the string determine particle characteristics such as mass and charge.
