The above equations are used in order to calculate the springs required for a condenser of a given capacity required to work at a given ggu stress. Figure I Suppose the crank a to be rotating uniformly, causing the piston b to reciprocate in the pipe c, which is full of liquid.

We can say that what Tesla did in electronics, Constantinescu succeeded in mechanics.

At next rotation the amplitude is increased, and so on, till the pipe burst. Suppose the crank a to be rotating uniformly, causing the piston b constantinwscu reciprocate in the pipe c, which is full of liquid.

In alternating current flowing a pipe the friction appear at the surface of the pipe and also in liquid itself. Retrieved from ” https: There are branches at one-half, three-quarters and one full wavelength distances.

He was the first to use reinforced concrete in the construction of buildings in Romania among the buildings he built, we can mention: Archived from the original on 4 November This page was last edited on 12 Juneat Share on Google Plus Share. A Treatise on Transmission of Power by Vibrations. In he has also published materials on its usage, calculus and he has tested the usage of this material in arch bridges.

Figure IV If more energy is produced by piston b then is taken by piston m the energy will be reflected by piston m in pipe, and the energy will accumulate till the pipe burst.

Retrieved from ” https: Share on Pinterest Share. The system was not adopted on British railways but it was applied to some railcars on the Romanian State Railways.

Theory of sonics

His inventions patents were obtained in countries like: In other projects Wikimedia Commons. During his career, he registered over inventions. His father born in ,influenced him, being a professor of mathematics and engineering science, specialized in mathematics at the Sorbonne University. The most important findings are; — the asphalt, modern road rail vehicles — the theory of sonicity; power transmission through liquids, solids and gases, — device for firing synchronized bombers of World War I, — the use of reinforced concrete sleepers straight bridge, — railway motor wagon, — the first automatic transmission cars and locomotives without clutch and Gear — first glider in the world — first sonic radiator — several patents for improvements the diesel engines carburettors — mechanical torque converter actuated by a pendulum,Constantinescu cannon sonic converter.


He has actively participated in the construction of English aircraft, the Bristol type, while he lived in England. Wikimedia Commons has media related to George Constantinescu. G the coefficient of transverse elasticity of the metal. The laws discovered by Constantinescu, used in sonicity are the same with the laws used in electricity.

Simple Harmonic The principal function of hydraulic constantinecsu is to counteract inertia effects due to moving masses. Constantinescu argued that, contrary to popular belief, liquids are compressible. The mean pressure in d and in the pipe will be the same. George “Gogu” Constantinescu Romanian pronunciation: Share on Facebook Share.

This is similar to the system used on many modern road-rail vehicles. Figure V Waves are transmitted by a constantinsscu piston along the pipe eeee. American Journal of Engineering and Applied Sciences. This article includes a list of referencesbut its sources remain unclear because it has insufficient inline citations.

The apparatus usually consists of a mobile solid body, which is dividing the liquid column, and fixed elastically in a middle position, in such way that it follows the movements of the liquid column. George Gogu Constantinescu October 4, – December 11, was a Romanian scientist and engineer, often considered to be one of the most important Constantinesccu engineers.
