Mechanical Engineering Design I
Mechanical Engineering Design I, is the first edition of a largest old preocupation of the authors in this field. It presents the design of the Otto Motors, kinematics and dynamics, a new Otto engine, the efficiency of the engines with internal combustion, the design of the V engines, the design of the distribution mechanisms, the design of the power train and the design of the drivetrain. It presents as well the design of the planetary trains with their real efficiency. The book has 14 chapters. Since the predominant component in all chapters is the dynamics, the book might be called and dynamic design in mechanical engineering.
The Aviation History
According to Aulus Gellius, Archytas, the Ancient Greek philosopher, mathematician, astronomer, statesman, and strategist, was reputed to have designed and built, around 400 BC, the first artificial, self-propelled flying device, a bird-shaped model propelled by a jet of what was probably steam, said to have actually flown some 200 metres. This machine, which its inventor called The Pigeon, may have been suspended on a wire or pivot for its flight. The 9th century Muslim Berber inventor, Abbas Ibn Firnas's glider is considered by John Harding to be the first attempt at heavier-than-air flight in aviation history. In 1010 AD an English monk, Eilmer of Malmesbury purportedly piloted a primitiv...
Presentation of Romanian Engineers Who Contributed to the Development of Global Aeronautics - Part I.
It is said that "the Romanian is born poet". And so it is, but we could say rather that "the Romanian is born and an engineer", having deeply embedded himself, the vocation of the builder, the innovator, the inventor. The great cathedrals, the beautiful monasteries built, or even the churches and churches (built or wooden) clearly show this vocation. After centuries, the "Voroneţ blue" still retains its vivid colors, even on the outer walls, beaten by rain, snow and wind. Suveica, the loom of war, the potter's wheel, the water and windmills, the musical instruments, the wells or the fountains, the agricultural tools, the traditional Romanian houses with porch, are only some proofs of the fo...
Camshaft Precision
In the first chapter the authors present an original method to calculate the efficiency of the cams mechanisms. The second chapter presents an original method in determining a general, dynamic and differential equation for the motion of machines and mechanisms, particularized for the mechanisms with rotation cams and followers. The third chapter presents an original method to determine the general dynamics of mechanisms with rotation cams and followers, particularized to the plate translated follower. First, it presents the dynamics kinematics. Then it solves the Lagrange equation and using an original dynamic model with one degree of freedom, with variable internal amortization, it makes th...

Green Energy
Energy development is the effort to provide sufficient primary energy sources and secondary energy forms for supply, cost, impact on air pollution and water pollution, mitigation of climate change with renewable energy. Technologically advanced societies have become increasingly dependent on external energy sources for transportation, the production of many manufactured goods, and the delivery of energy services. This energy allows people who can afford the cost to live under otherwise unfavorable climatic conditions through the use of heating, ventilation, and/or air conditioning. Level of use of external energy sources differs across societies, as do the climate, convenience, levels of tra...

A New Doppler Effect
The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842 in Prague, is the change in frequency of a wave for an observer moving relative to the source of the wave. It is commonly heard when a vehicle sounding a siren or horn approaches, passes, and recedes from an observer. The received frequency is higher (compared to the emitted frequency) during the approach, it is identical at the instant of passing by, and it is lower during the recession. The relative changes in frequency can be explained as follows. When the source of the waves is moving toward the observer, each successive wave crest is emitted from a position closer to the obser...
