Mechanical Engineering Design 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...

The McDonnell Douglas (now Boeing) F/A-18 Hornet is a twin-engine supersonic, all-weather carrier-capable multirole fighter jet, designed to dogfight and attack ground targets (F/A for Fighter/Attack). The Lockheed AC-130 gunship is a heavily-armed ground-attack aircraft variant of the C-130 Hercules transport plane. The Bell AH-1 SuperCobra is a twin-engine attack helicopter based on the US Armys AH-1 Cobra. The Boeing AH-64 Apache is a four-blade, twin-engine attack helicopter with a tailwheel-type landing gear arrangement, and a tandem cockpit for a two-man crew. The Northrop T-38...

The movement of an electron around the atomic nucleus has today a great importance in many engineering fields. Electronics, aeronautics, micro and nanotechnology, electrical engineering, optics, lasers, nuclear power, computing, equipment and automation, telecommunications, genetic engineering, bioengineering, special processing, modern welding, robotics, energy and electromagnetic wave field is today only a few of the many applications of electronic engineering. This first chapter presents shortly a new and original relation which calculates the radius with that the electron is running...

Development and diversification of machines and mechanisms with applications in all areas of scientific research requires new systematization and improvement of existing mechanical systems by creating new mechanisms adapted to the modern requirements, which involve more complex topological structures. Modern industry, the practice of engineering design and manufacture increasingly rely more on scientific research results and practical. The processes of robotisation of today define and influence the emergence of new industries, with applications in specific environmental conditions, handling...

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...

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...

Nuclear fusion is the process by which two or more atomic nuclei join together, or "fuse," to form a single heavier nucleus. During this process, matter is not conserved because some of the mass of the fusing nuclei is converted to energy which is released. The binding energy of the resulting nucleus is greater than the binding energy of each of the nuclei that fused to produce it. Fusion is the process that powers active stars. Creating the required conditions for fusion on Earth is very difficult, to the point that it has not been accomplished at any scale for protium, the common light...

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...

Larger STOVL designs were considered, the Armstrong Whitworth AW.681 cargo aircraft was under development when cancelled in 1965. The Dornier Do 31 got as far as three experimental aircraft before cancellation in 1970. Although mostly a VTOL design, the V-22 Osprey has increased payload when taking off from a short runway. The Hawker Siddeley Harrier, colloquially the \"Harrier Jump Jet\," was developed in the 1960s and was the first generation of the Harrier series of aircraft. It was the first operational close-support and reconnaissance fighter aircraft with Vertical/Short Takeoff and...
