Multidisciplinary Design Project Engineering Dictionary Version 0.0.2 February 15, 2006 . DRAFT Dr. Depak Muniraj http://depakmuniraj.blogspot.in/ Cambridge-MIT Institute Multidisciplinary Design Project This Dictionary/Glossary of Engineering terms has been compiled to compliment the work developed as part of the Multi-disciplinary Design Project (MDP), which is a programme to develop teaching material and kits to aid the running of mechtronics projects in Universities and Schools. The project is being carried out with support from the Cambridge-MIT Institute undergraduate teaching programe.

DRAFT 2 CMI-MDP Programme Dr. Depak Muniraj http://depakmuniraj.blogspot.in/ 1 Introduction This dictionary/glossary has not been developed as a definative work but as a useful reference book for engi- neering students to search when looking for the meaning of a word/phrase. It has been compiled from a number of existing glossaries together with a number of local additions. Each reference has a standard layout Transistor [Elec] Where [Elec] indicates the engineering area where the definition is used and the original source, see section 1.1. In a number of cases there are multiple definitions, these have been kept to indicate the variation in use even within the same industry. The MDP project is very grateful to the compilers of the other collections for their kind permission to reuse their data, but accepts responsibility for any errors or mistranscription. Links to some of the original data sources are given in section 1.1 and the users is urged to consult these if additional information is required. 1.1 Engineering Disciplines Aerospace & thermodynamic engineering involves developing, designing, testing items related to aircraft power generating systems. • [aeroth] - general Agricultural & Food engineering involves every aspect of food production, processing, marketing, and distribution. Biomedical engineering applies engineering principles and design to the biology and medical arena to improve health care and the lives of those with medical impairments. Bringing together knowledge from many engineering disciplines and technical fields, biomedical engineers design medical instruments, devices, and software; develop new procedures; conduct research; and solve clinical problems. Chemical engineering applies principles of chemistry and physics to the design and production of materials that undergo chemical changes during their manufacture. Civil & Structural engineering involves planning, designing, and building a wide variety of structures and fa- cilities, including bridges, roads and highways, dams, high-rise buildings, airports, water treatment centers, industrial manufacturing and processing facilities, and sanitation plants. • [civilst] - general • [civil-1] - see http://urban.arch.virginia.edu/km6e/reference/glossary/struc-glossary.html Computer & Software engineering involves the design, construction, and operation of computer systems. • [soft] - general • [soft1] - see http://www.apl.jwww.apl.jhu.edu Control Systems engineering involves the design and manufacture of instrumentation and ways to control dynamic processes automatically. Electrical & Electronic engineering is the practical application of electricity. Covering the area from very low power/voltage to high power and transmission systems. • [elec] - general Environmental engineering is the development of processes and infrastructure for the supply of water, the disposal of waste, and the control of all kinds of pollution. • [enviro] - general Geotechnical engineering uses the principles of mechanics to analyze and predict the behavior of earth materials in engineering situations.DRAFT CMI-MDP Programme 3 Dr. Depak Muniraj http://depakmuniraj.blogspot.in/ • [geotech] - general Instrumental engineering • [instrum] - general • [instrum-1] - see http://www.omega.com Manufacturing engineering includes all aspects of manufacturing operations, including the behavior and properties of materials and materials processes; the design of products, equipment, and tooling neces- sary for their manufacture; management of manufacturing enterprises; and, the design and operation of manufacturing systems Materials engineering focusses on materials design, testing and processing techniques (e.g. casting, rolling, welding) • [mat] - general • [mat-1] - see http://www.justinline.com/glossary Mechanical engineering applies the principles of mechanics and energy to the design of machines and devices. Perhaps the broadest of all engineering disciplines, mechanical engineering is generally combined into three broad areas: energy, structures and motion in mechanical systems, and manufacturing. • [mech] - general • [mech-1] - materials related see http://www.tulane.edu/ bmitche/book/glossary.html • [mech-2] - Welding http://www.meg.co.uk • [mech-3] - Fasteners see http://www.boltscience.com Mining engineering comprises all aspects of discovering, removing, and processing minerals from the earth. Nuclear engineering involves the design, construction, and operation of nuclear power plants for power gen- eration, propulsion of nuclear submarines, the handling of nuclear fuels and the safe disposal of radioactive wastes. • [nuclear] - general • [nuclear-1] - see http://www.usanuclear Petroleum engineering involves sustaining the flow of oil and gas, including discovery, recovery, storage, and transportation of petroleum. • [petro] - general • [petro-1] - see http://www.statoil.com Sanitary engineering is a branch of civil and environmental engineering that deals with sanitary issues affecting public health, such as safe drinking water and sewage disposal. Among other things, sanitary engineers deal with preventing toxins and dangerous microorganisms from endangering the public in such systems.
