Concept of the Dispersion of Electric and Magnetic Inductivitiesand its Physical Interpretation
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 14 Issue: 8
In a number of scientific publications is asserted that the permittivity and permeability of material media depends on frequency. But even Maxwell himself, who was the author of the basic equations of electrodynamics, believed that ε and μ were frequency-independent fundamental constants. The article shows that Max well was right, and the recognition of the presence of disp...

Simulation of Gear Dynamics by Circuit Theory Methods
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 14 Issue: 8
A methodology of study of gear dynamics with the aid of the circuit theory and linear graph methods is presented. In terms of analogy of the force, electric tension is used for the composition of equivalent electrical circuit, which immediately gives the equations of motion. The application of the electrical analogy method for the automation of composition of equation of motion and their...

Analysis of an NACA 4311 Airfoil for Flying Bike
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 14 Issue: 7
The development of the wing has been always such that it should be able to produce the maximum lift due to the high pressure on the bottom surface and low pressure on the top surface of an airfoil. And these concepts clears that the flow of air/velocity of air will be low on the lower surface and higher on the upper surface of an airfoil. So, due to these differences in pressures and vel...

An Inhomogeneous Gravitational Field and the Body without Center of Gravity
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 14 Issue: 8
Concept of homogeneity (or inhomogeneity) of the gravitational field is a rather specific one. Namely, according to the Newton`s law of gravitation, either intensity or direction, or each of these two characteristics of the gravitational force acting on the body, depend on its position in the gravitational field. So, in fact, for the body as a whole, the gravitational field is always an ...

Effect of Compression Ratio and Exhaust Gas Recirculation (EGR) on Combustion, Emission and Performance of DI Diesel Engine with Biodiesel Blends
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 14 Issue: 7
The present investigation deals with combustion, emission and performance characteristics of a single cylinder DI diesel engine for biodiesel blends (J10, J20, J30, P10, P20, P30) with the optimum use of EGR system by the formulation of matrix analysis. Compression ratios like 17.5:1, 19:1, 20:1 were varied. The piston was modified by cold metal transfer (CMT) welding with the use of alu...

Importance of Lathe Machine in Engineering Field and its usage
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 14 Issue: 6
The lathe, probably one of the earliest machine tools, is one of the most versatile and widely used machine tool, so also known as mother machine tool. An engine lathe is the most basic and simplest form of the lathe. It is called so because in early lathes, power was obtained from engines. The job to be machined is held and rotated in a lathe chuck; a cutting tool is advanced which is s...

A Thermal Modeling to Predict and Control the Cutting Temperature. The Simulation of Face-Milling Process
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 14 Issue: 6
This paper presents a new procedure to evaluate the cutting temperature milling. In HSM. The study of the thermal behavior is important because the life expectancy of a cutting tool is limited by its temperature: the higher the temperature, the shorter its life. Tests made on many uncoated tools at stand still, after milling, have shown that there is an important drop for the temperature...
