Circular plate capacitor with different discs

Finite Plate with Circular and Square Hole under Partial Loading

In this paper a general analytical solution is obtained to find stress distribution in a finite elastic plate with a circular or square hole subjected to arbitrary biaxial partial loading using modified boundary condition by assuming plane stress conditions. The method employed is based on solution of circular hole in finite rectangular plate. This plate is mapped to circular ones and the parti...

The Difficulty of Centering Circular Discs

Centering, positioning an object within specified bounds, is a common computer task, for example making selections using a touch screen or positioning icons relative to each other. The experiments measured times for participants (n = 155) to position a circular cursor with diameter, p = 40 pixel or approximately 10 mm, completely within circular targets with a variety of diameters, w. The analy...

Thermodynamic energy exchange in a moving plate capacitor.

In this paper we describe an apparent paradox concerning a moving plate capacitor driven by thermal noise from a resistor. The plates are attracted together, but a demon restores the plates of the capacitor to their original position when the voltage across the capacitor is small-hence only small forces are present for the demon to work against. The demon has to work harder than this to avoid t...

Chaotic motion of a bimetallic circular plate

Considering the effect of geometric nonlinearity and uniformly distributed time-varying temperature, the bifurcation behaviors and chaotic phenomena of a bimetallic thin circular plate are investigated. First of all, the nonlinear dynamic equation for bimetallic plate is established and further reduced to Duffing equation of harmonic parametric excitation, from which the pitchfork bifurcation p...
