Key-Hole Notches in Isostatic Graphite: A Review of Some Recent Data

Filippo Berto, A. Gagani, Relly Victoria V. Petrescu and Florian Ion T. Petrescu
Fracture of the breakable isostatic graphite is concerned using the experimental and theoretically, the plates containing nicks holes key subject to varying degrees of mixed task. The main purpose of this work is a double one. In the first place, in order to offer a new set of experimental results on fracture of samples of graphite scored, with different values of the load mixed and radii notch and which may be helpful for researchers, as it enlarges the very limited data available; and secondly...

Electron Dimensions

Relly Victoria Virgil Petrescu, Raffaella Aversa, Shuhui Li, MirMilad Mirsayar, Ronald Bucinell, Samuel P. Kozaitis, Taher M. Abu-Lebdeh, Antonio Apicella and Florian Ion Tiberiu Petrescu
In this study, the theoretical principles necessary to determine the exact magnitude of a moving electron, depending on the speed of movement, will be exposed. The equations are specifically discussed to determine the radius R of the moving electron, which refers to the electron movement velocity v and the resting mass m0. The mechanical moment of inertia of a sphere around one of its diameters is determined by the relationship between the total kinetic energy of a moving electron as the sum of ...

Geometrical Synthesis of the Distribution Mechanisms

Florian Ion Tiberiu Petrescu
In this study the author presents shortly some few original trigonometric methods to make the synthesis of some main distribution mechanisms. One presents four main modules of distribution mechanisms, with rotary cam and translated or rotated tappet plane or with roll, used with priority at the distribution mechanisms from the heat engines with internal combustion. These types of distribution mechanisms can improve the changes of gases and may decrease significantly the level of vibration, noise...
