Last summer , it was very expensive to fill up a gas tank when the gasoline price hit close to four dollars a gallon. Transportation by road or air consumes fuel, which not only increases our vulnerability to foreign imports but also is a source of greenhouse gas emissions that will impact adverse change in climate and global warming. A mechanical engineer at Washington University in St. Louis is developing techniques that will lessen our monetary pain at the pump by reducing the drag of vehicles — planes, autos and trucks. Drag is an aerodynamic force that is the result of resistance a body encounters when it moves in a liquid or gaseous medium (such as air). Reduction in drag means less fuel would be required to overcome the fluid resistance encountered by the moving vehicle.

The lifting industry in India is at a turning point, as rapid development makes modern construction equipment a better option for many users than cheap manual labour. While local manufacturers have been building truck cranes in India since before the country’s independence, overseas manufacturers are only now beginning to make an entry into the market.

Part 1 - Variable nozzle turbines (VNT) were supposed to be the killer turbo technology - the wastegateless design able to be matched to engines to give excellent response throughout the rev range. And, while they have been adopted in huge numbers in diesel engine applications, problems associated with the high exhaust gas temperatures of petrol engines have continued to prevent their more widespread use in passenger cars. Part2 - No matter how well it is matched to an engine, a turbocharger still has poor low-load performance. This is because the performance of the compressor (the part of the turbo that pumps air into the engine) is dependent on its speed of rotation. Since it is connected straight to the turbine, before the compressor can turn quickly enough to move significant amounts of air into the engine, there needs to be sufficient exhaust gas flow to whiz the turbine around. |

It started as an engineering concept at the turn of the 21st century -- gas-electric "hybrid" dream cars displayed at auto shows to gauge public reaction and market potential. But within just a few years (a wink of time in vehicle development terms), hybrids have evolved into one of today's most important automotive trends. |

Materials failure is of central importance to many technologies, from electronic devices to armour and from solar cells to coatings. When a brittle material (such as a ceramic, an oxide or a semiconductor) is loaded to the limit of its strength, it fails by nucleation and propagation of a crack. The conditions for crack propagation, which determine when the material will fail, depend on macroscopic parameters such as the geometry and dimensions of the specimen. The way the crack propagates, however, is entirely determined by atomic-scale phenomena, since brittle crack tips are atomically sharp and propagate by breaking the variously oriented interatomic bonds, one at a time, at each point of the moving crack front. |

When the gears used in the back axle of his beloved Lanchester failed on a recent trip to France, Peter Noble, after months of searchingthe world, turned to Renold Gears for a solution. Driving through thefringes of the Gobi Desert in his 1955 Bentley Continental Peter resolved to buy a car more suitable for such pioneering motoring roads andin 1991 bought a 1925 Lanchester 40HP Tourer, one of only 7 left handdrive cars ever made. A chance viewing of the Whicker’s World series:`Princes of India’, where an interview was conducted in a 1923 Lanchester 40HP belonging to the Maharaja of Alwar had awakened Peter to theLanchester marque. This 3 ton touring car with full weather protectionwould make an ideal transport for crossing Continents on unused roadsor desert tracks. |

Diesel engines are so all-encompassing in agriculture, it's hard to imagine life without them. Andy Collings looked back at the man who started it all – Rudolf Diesel
While the development of the diesel engine is usually attributed to Rudolf Diesel, there's always been some dispute as to whether or not he was the true inventor of what is now known as the compression ignition engine. |

Al Zamil Metal Works Factory (AZMWF), the pioneer in the region in using the Tank Jacking System , is breaking new ground in the repair and refurbishment of tank base. The company, well known in Saudi Arabia, has always adopted a systematic approach to utilizing the jacking system in constructing steel tanks, says Capt Ahmed Al-Tabei, assistant general manager, Al-Zamil Metal Works Factory.
AZMWF is credited with setting records in the tank manufacturing industry in Saudi Arabia when it erected the Dome Roof Tank (31.7 metre diameter by jacking system). The tank has a capacity of four million gallons. The structure became the fresh water storage tank for Al Khafji joint operations, KGOC/AGOC (Kuwait Gulf Oil Company and Aramco Gulf Oil), operating with a consortium of SETE Energy SA and Carlo Gavazzi.
In recent developments, AZMWF has entered into a relationship with BYGGWIK (UK) Ltd, the UK based manufacturer of Tank Jacking System. |

Craftsman has designed triforms so as to better use the tool clearances when the faces are set at an angle of 120 degree, as opposed to the usual 90 degrees of the more commonly found cubes.
In this instance, the large workpieces need only three operation setups, so the choice of a three-sided column was obvious and the only way to maximise machine productivity.
Robert Johnson, Craftsman Tools managing director, said: “The seven triforms are part of our standard workholding range. We have then adapted the units individually for the client’s specific needs.

Gems of engineering : the floating crane. Because the cranes require a massive superstructure and a relatively shallow hull, designers have to approach them pretty much the opposite way they approach typical ship design. They weigh many thousands of tons, and yet somehow manage to lift thousands of tons, too—engineering that truly borders on magic.
