| Abstract from DBPedia | Mechanical engineering is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the engineering branches. The mechanical engineering field requires an understanding of core areas including mechanics, dynamics, thermodynamics, materials science, structural analysis, and electricity. In addition to these core principles, mechanical engineers use tools such as computer-aided design (CAD), computer-aided manufacturing (CAM), and product lifecycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, watercraft, robotics, medical devices, weapons, and others. It is the branch of engineering that involves the design, production, and operation of machinery. Mechanical engineering emerged as a field during the Industrial Revolution in Europe in the 18th century; however, its development can be traced back several thousand years around the world. In the 19th century, developments in physics led to the development of mechanical engineering science. The field has continually evolved to incorporate advancements; today mechanical engineers are pursuing developments in such areas as composites, mechatronics, and nanotechnology. It also overlaps with aerospace engineering, metallurgical engineering, civil engineering, structural engineering, electrical engineering, manufacturing engineering, chemical engineering, industrial engineering, and other engineering disciplines to varying amounts. Mechanical engineers may also work in the field of biomedical engineering, specifically with biomechanics, transport phenomena, biomechatronics, bionanotechnology, and modelling of biological systems.機械工学（きかいこうがく、英語: mechanical engineering）とは、機械あるいは機械要素の設計、製作などから、機械の使用方法、運用などまでの全ての事項を対象とする工学の一分野である。 具体的には、熱力学、機械力学、流体力学、材料力学の四力学を基礎とした機械の設計や製作のための技術を学ぶほか、より広義には、機構学、制御工学、経営工学、材料工学（金属工学）、そして近年のコンピュータ化に対応したハードウェア及びソフトウェア技術全般を研究対象としている。 (Source: http://dbpedia.org/resource/Mechanical_engineering) |
