Electromagnetic rotation experiment of Faraday, ca. 1821 [2] Working principle of a homopolar motor: due to movement of negative charges from center towards rim of the disk, a Lorentz force F L is created which brings the entire disk into rotation. The homopolar motor was the first electrical motor to be built.
Even if a live person is present, the automation system at commercial stations usually picks the music ahead of time out of the current rotation, thus the DJ becomes only an announcer. Heavy rotation or power rotation is a list of songs that get the most airplay on a radio station. Songs in heavy rotation will be played many times in a 24-hour ...
In geometry the rotation group is the group of all rotations about the origin of three-dimensional Euclidean space R 3 under the operation of composition. [1] By definition, a rotation about the origin is a linear transformation that preserves length of vectors (it is an isometry) and preserves orientation (i.e. handedness) of space.
TikTok has plans for another appeal as it faces a ban on January 19. The DC Circuit Court of Appeals on Friday rejected a temporary pause on the ban of TikTok, calling such a block “unwarranted ...

Subway is celebrating the new year with some new menu options, as well as a fresh take on a Southwestern-inspired sub!. On Monday, Jan. 6, the quick-service sandwich chain announced two new ...
Rotating unbalance is the uneven distribution of mass around an axis of rotation. A rotating mass, or rotor, is said to be out of balance when its center of mass (inertia axis) is out of alignment with the center of rotation (geometric axis). Unbalance causes a moment which gives the rotor a wobbling movement characteristic of vibration of ...
