Mechanical Engineering
Mechanical engineering is the study of physical machines and mechanism (engineering), mechanisms that may involve force and movement. It is an engineering branch that combines engineering physics and engineering mathematics, mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the List of engineering branches, engineering branches. Mechanical engineering requires an understanding of core areas including mechanics, Analytical dynamics, dynamics, thermodynamics, materials science, design, structural analysis, and electricity. In addition to these core principles, mechanical engineers use tools such as computer-aided design (CAD), computer-aided manufacturing (CAM), computer-aided engineering (CAE), and product lifecycle management to design and analyze manufacturing plants, industrial equipment and industrial machinery, machinery, HVAC, heating and cooling systems, transport systems, ...

Materials Science And Engineering (journal)
Materials science is an interdisciplinary field of researching and discovering materials. Materials engineering is an engineering field of finding uses for materials in other fields and industries. The intellectual origins of materials science stem from the Age of Enlightenment, when researchers began to use analytical thinking from chemistry, physics, and engineering to understand ancient, phenomenological observations in metallurgy and mineralogy. Materials science still incorporates elements of physics, chemistry, and engineering. As such, the field was long considered by academic institutions as a sub-field of these related fields. Beginning in the 1940s, materials science began to be more widely recognized as a specific and distinct field of science and engineering, and major technical universities around the world created dedicated schools for its study. Materials scientists emphasize understanding how the history of a material (''processing'') influences its structure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scientific American
''Scientific American'', informally abbreviated ''SciAm'' or sometimes ''SA'', is an American popular science magazine. Many scientists, including Albert Einstein and Nikola Tesla, have contributed articles to it, with more than 150 Nobel Prize-winners being featured since its inception. In print since 1845, it is the oldest continuously published magazine in the United States. ''Scientific American'' is owned by Springer Nature, which is a subsidiary of Holtzbrinck Publishing Group. History ''Scientific American'' was founded by inventor and publisher Rufus Porter (painter), Rufus Porter in 1845 as a four-page weekly newspaper. The first issue of the large-format New York City newspaper was released on August 28, 1845. Throughout its early years, much emphasis was placed on reports of what was going on at the United States Patent and Trademark Office, U.S. Patent Office.

Split-Hopkinson Pressure Bar
The split-Hopkinson pressure bar (SHPB), named after Bertram Hopkinson, sometimes also called a Kolsky bar, is an apparatus for testing the dynamic stress– strain response of materials. History The Hopkinson pressure bar was first suggested by Bertram Hopkinson in 1914 as a way to measure stress pulse propagation in a metal bar. Later, in 1949 Herbert Kolsky refined Hopkinson's technique by using two Hopkinson bars in series, now known as the split-Hopkinson bar, to measure stress and strain, incorporating advancements in the cathode ray oscilloscope in conjunction with electrical condenser units to record the pressure wave propagation in the pressure bars as pioneered by Rhisiart Morgan Davies a year earlier in 1948. Later modifications have allowed for tensile, compression, and torsion testing. Operation Although there are various setups and techniques currently in use for the split-Hopkinson pressure bar, the underlying principles for the test and measurement are the sam ...

Fast Company (magazine)
''Fast Company'' is an American business magazine published monthly in print and online, focusing on technology, business, and design. It releases six print issues annually. History ''Fast Company'' was founded in November 1995 by Alan Webber and Bill Taylor, both former '' Harvard Business Review'' editors, and publisher Mortimer Zuckerman. Early competitors included '' Red Herring'', '' Business 2.0'' and '' The Industry Standard''. In 1997, ''Fast Company'' created an online social network called the "Company of Friends," which led to the formation of numerous meeting groups. At its peak, the Company of Friends comprised over 40,000 members across 120 cities, though membership declined to 8,000 by 2003. In 2000, Zuckerman sold ''Fast Company'' to Gruner + Jahr, majority-owned by media giant Bertelsmann, for $550 million. The sale coincided with the dot-com bubble burst, resulting in substantial losses and a drop in circulation. Webber and Taylor departed in 2002, a ...

Fly Ash
Coal combustion products (CCPs), also called coal combustion wastes (CCWs) or coal combustion residuals (CCRs), are byproducts of burning coal. They are categorized in four groups, each based on physical and chemical forms derived from coal combustion methods and emission controls: * Fly ash is captured after coal combustion by filters (Dust collector#Fabric filters, bag houses), electrostatic precipitators and other air pollution control devices. It comprises 60 percent of all coal combustion waste (labeled here as coal combustion products). It is most commonly used as a high-performance substitute for Portland cement or as Cement clinker, clinker for Portland cement production. Cements blended with fly ash are becoming more common. Building material applications range from grouts and masonry products to cellular concrete and roofing tiles. Many asphaltic concrete pavements contain fly ash. Geotechnical applications include soil stabilization, road base, structural fill, embankmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS Zumwalt
USS ''Zumwalt'' (DDG-1000) is a guided missile destroyer of the United States Navy. She is the lead ship of the and the first ship to be named after Admiral Elmo Zumwalt. ''Zumwalt'' has stealth capabilities, having a radar cross-section similar to a fishing boat despite her large size. On December 7, 2015, ''Zumwalt'' began her sea trial preparatory to joining the Pacific Fleet. The ship was commissioned in Baltimore on October 15, 2016. Her home port is San Diego, California. In late 2024, the AGS was removed and replaced with the IRCPS weapon system. Namesake ''Zumwalt'' is named after Elmo Russell Zumwalt Jr., who was an American naval officer and the youngest man to serve as the Chief of Naval Operations.
