Analytical formulas are obtained for determining the times of transition from rotational to oscillatory motion, as well as for the critical angular velocity of beyond-the-atmosphere rotation. When this critical velocity is exceeded, body rotation proceeds for a long time interval (planar autorotation ...
A rhombus has four equal sides but of varying angles. A rhombus has two lines of symmetry (vertical and horizontal), an order of two, and the angle of rotation of 180 degrees. Also Check: Line Symmetry or Reflection Symmetry Rotational Symmetry ...
a light source would be directed onto the rotor R from a position above the substrate. The light source could be any type of optical signal. The rotor plate could also serve as a paddle for inducing and/or detecting fluid motion in microfluidics systems, as a gated catalyst in wet chemistr...
(Refs3,4). Such a nanometer scale electromechanical system is described below, demonstrating the construction and successful operation of a fully synthetic nanoscale electromechanical actuator/motor incorporating a rotatable metal plate, with a multi-walled carbon nanotube serving as the key motion-...
the effective eccentricity parameter defined in the present model is quite small ( eeff = 0.01) and there was apparently no mechanical connection between the bead and the cantilever to couple the beam rotation to the particle's rotational motion (i.e., local rolling contact was not prevented)....
