In this paper, rotating thick-walled hollow cylindrical shell composed of functionally graded material are analyzed by using the theory of hyperelasticity.
"But 100 years ago, we only had a few seismographs working on carbon paper rotating on cylinders and drums, so before 1900 we're better off using historical records, if there are any".
The effects of non-synchronous rotating damping, i.e., of energy dissipation in elements rotating at a speed different from that of the main rotor, on the dynamic behaviour of the latter have been already studied in a previous paper (J. Rotating Machinery 6 (6) (2000)) for the case of non-gyroscopic rotating systems.
If you "walk" the compass in a line along a sheet of paper by rotating one arm in front of the other, the compass always ends up in the same symmetry after each step.
In this paper, the rotating parts of a bladed-rotor system are further subdivided into the rotor blade-group and the other rotating components.
In the original 1993 study, Gordon L. Shaw and Frances H. Rauscher showed that a small group of college students performed better on certain spatial-reasoning tests after listening to a Mozart sonata -- "seeing" the design of a snowflake, for example, after mentally cutting and folding a piece of paper, or rotating and comparing objects conceptually in space.
In this paper, a rotating rod electrode disk is introduced as a hydrodynamic electrode and both the electrolyte flow hydrodynamics as well as mass transport towards the disk were investigated and compared with the rotating disk electrode.
Every time the note is pinched, the analog data was recorded and that paper was rotated 90 degrees.
In this paper, subspace rotating technique has been introduced into the problem (10) which is inspired by the methods contributed by [22, 23].
The selected hard seeds were scarified using a Forsberg scarifier (a drum lined with P100-grit sand paper) and rotated for 20 seconds at 1425 revolutions per minute to abrade the seed coat.
