This detailed article is based upon history , projects and what does a mechanical engineer do.
History Of Mechanical Engineering:
The history mechanical engineering dates back to the ancient and medieval history of the mankind when the human beings tried to invent machines which could solve their problems using the principles of mechanics and physics. The contribution in the field of mechanical engineering of the ancient Greeks is worth mentioning the first steam engine was also developed by the ancient Greeks, The ancient Chinese build the first water clock and seismometer somewhere between 1st and 2nd century, whereas during the 15th and 16th century many Muslim engineers also made notable contributions in the field of mechanical engineering.
The most Important advances in the field of mechanical engineering transpired in Great Britain during the late 17th century when an English scientist Sir Isaac Newton both formulated his famous three Laws of Motion and also developed Calculus. Later on, after the industrial revolution the field of mechanical engineering grew phenomenally and during 19thcentury.
Many countries like Great Britain, Scotland and Germany developed this field as separate filed of inside the field of Engineering and sole purpose of it was to manufacture and the designs machines and its engines using this holistic approach. As the industries grew so does the demand for machines and new innovations within the field of mechanical engineering were made in late 19th century the professional society for mechanical engineers were formed in USA and also in Great Britain, both of these societies were dedicated to the research and development in the field of mechanical engineering.
How to become a mechanical engineer:
To become a mechanical engineer a person is required to take a formal education in the form of bachelor degree in mechanical engineering and the degrees in this field of mechanics are offered at many universities worldwide. The courses within the program of mechanical engineering include mathematics, physical sciences and also the courses related to designing and graphics. Unlike other programs the mechanical engineering program is more focused on the practical application of concepts and less on the theoretical aspects of the programs.
Universities may give emphasis to do internships in order to prepare students for the practical work in industry. Certain colleges and universities offer a degree in mechanical engineering with the time scale of 5 years in which a student gets both bachelors and masters degree in 5 years. Several 5-year cooperative plans merge what the student has learned in the class with practical work, this enables student to acquire useful experience and also enable students to earn money and finance part of their education.
In USA ABET which is an independent accreditation agency also accredits programs in mechanical engineering. Large number of employers choose to employ students from an accredited program. In USA it is necessary to get a degree from ABET accredited program to become a licensed mechanical engineer. Let us discuss in details what does a mechanical engineer do.
What does a mechanical engineer do
Mechanical engineers are classically involved with the number of activities such as the
- designing ,analyzing and then producing the machine systems and the control
- automation of manufacturing systems;
- the management of materials;
- the production, dispersal, and depletion of energy resources;
- the design and elaboration of machines; and
- the elucidations to environmental problems, global warming being the most important environmental challenge that mechanical engineers are facing right now.
The designs of their machines must be made in such a way which will have minimum possible effect on the environment. Some other actions that mechanical engineers perform are testing and manufacturing design, operations, administration, marketing and research and development.
Furthermore, in addition to the above mentioned main mechanical engineering operations, large number of mechanical engineers also perform more specialized functions in the field of robotics, transport and logistics, control systems, cryogenics, automotive engineering, vibration, fuel technology, optics, bio mechanics and others.
Among the other fields of engineering, mechanical engineers can be considered as personally more creative and are known for their extensiveness in knowledge and more versatile as compared to engineers in other fields because mechanical engineers perform wide range of tasks.
