Editing Mechanical engineering (section)

==Job duties==
Mechanical engineers research, design, develop, build, and test mechanical and thermal devices, including tools, engines, and machines.

Mechanical engineers typically do the following:
* Analyze problems to see how mechanical and thermal devices might help solve the problem.
* Design or redesign mechanical and thermal devices using analysis and computer-aided design.
* Develop and test prototypes of devices they design.
* Analyze the test results and change the design as needed.
* Oversee the manufacturing process for the device.
* Manage a team of professionals in specialized fields like mechanical drafting and designing, prototyping, 3D printing or/and CNC Machines specialists.

Mechanical engineers design and oversee the manufacturing of many products ranging from medical devices to new batteries. They also design power-producing machines such as electric generators, internal combustion engines, and steam and gas turbines as well as power-using machines, such as refrigeration and air-conditioning systems.

Like other engineers, mechanical engineers use computers to help create and analyze designs, run simulations and test how a machine is likely to work.

===License and regulation===
Engineers may seek [[licensing|license]] by a state, provincial, or national government. The purpose of this process is to ensure that engineers possess the necessary technical knowledge, real-world experience, and knowledge of the local legal system to practice engineering at a professional level. Once certified, the engineer is given the title of [[Professional Engineer]] United States, Canada, Japan, South Korea, Bangladesh and South Africa), [[Chartered Engineer]] (in the United Kingdom, Ireland, India and Zimbabwe), ''Chartered Professional Engineer'' (in Australia and New Zealand) or ''European Engineer'' (much of the European Union).

In the U.S., to become a licensed Professional Engineer (PE), an engineer must pass the comprehensive FE (Fundamentals of Engineering) exam, work a minimum of 4 years as an ''Engineering Intern (EI)'' or ''Engineer-in-Training (EIT)'', and pass the "Principles and Practice" or PE (Practicing Engineer or Professional Engineer) exams. The requirements and steps of this process are set forth by the [[National Council of Examiners for Engineering and Surveying]] (NCEES), composed of engineering and land surveying licensing boards representing all U.S. states and territories.

In Australia (Queensland and Victoria) an engineer must be registered as a Professional Engineer within the State in which they practice, for example Registered Professional Engineer of Queensland or Victoria, RPEQ or RPEV. respectively.

In the UK, current graduates require a [[BEng]] plus an appropriate master's degree or an integrated [[MEng]] degree, a minimum of 4 years post graduate on the job competency development and a peer-reviewed project report to become a Chartered Mechanical Engineer (CEng, MIMechE) through the [[Institution of Mechanical Engineers]]. CEng MIMechE can also be obtained via an examination route administered by the [[City and Guilds of London Institute]].<ref>{{Cite book|last=Sayeed|first=Ahmed|url=https://books.google.com/books?id=pzOyDwAAQBAJ&pg=PA51|title=You Could Be the Winner (Volume - II)|date=24 September 2019|publisher=Sankalp Publication|isbn=978-93-88660-66-2|language=en}}</ref>

In most developed countries, certain engineering tasks, such as the design of bridges, electric power plants, and chemical plants, must be approved by a [[professional engineer]] or a [[chartered engineer]]. "Only a licensed engineer, for instance, may prepare, sign, seal and submit engineering plans and drawings to a public authority for approval, or to seal engineering work for public and private clients."<ref>{{cite web |title= Why Get Licensed? |work= National Society of Professional Engineers |url=http://www.nspe.org/Licensure/WhyGetLicensed/index.html |access-date= 6 May 2008}}</ref> This requirement can be written into state and provincial legislation, such as in the Canadian provinces, for example the Ontario or Quebec's Engineer Act.<ref>{{cite web|title=Engineers Act |work=Quebec Statutes and Regulations (CanLII) |url=http://www.canlii.org/qc/laws/sta/i-9/20050616/whole.html |access-date=24 July 2005 |url-status=dead |archive-url=https://web.archive.org/web/20061005184956/http://www.canlii.org/qc/laws/sta/i-9/20050616/whole.html |archive-date=5 October 2006}}</ref>

In other countries, such as the UK, no such legislation exists; however, practically all certifying bodies maintain a [[Ethical code|code of ethics]] independent of legislation, that they expect all members to abide by or risk expulsion.<ref>{{cite web|title=Codes of Ethics and Conduct |work=Online Ethics Center |url=http://onlineethics.org/codes/ |access-date=24 July 2005 |archive-url=https://web.archive.org/web/20050619081942/http://onlineethics.org/codes/ |archive-date=19 June 2005 |url-status=dead}}</ref>
