Mechanical engineering deals with the fundamental principles of physics and engineering to design, analyze, manufacturing and the maintenance of the machinery or mechanical systems. It is perhaps one of the oldest and also one the widest fields of engineering. Simply if some one asks me, what is mechanical engineering, i will simply reply
It is the branch of engineering that involves the design, production, and operation of machinery.
Mechanical engineering applies the following concepts in order to operate or manufacture a machinery or mechanical system
- structural analysis,
- materials science,
- electricity and
Mechanical Engineers design and analyze manufacturing plants, industrial equipment and machinery, transport systems, heating and cooling systems, watercraft, aircraft, robotics, weapons, medical devices and others. 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
The ancient Chinese built the first water clock and seismometer. During the 15th and 16th century many Muslim engineers made notable contributions in the field of mechanical engineering. They invented crankshaft and camshaft that is still used as basic components.
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.
As the industries grew so does the demand for machines and new innovations within 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 a bachelor degree in mechanical engineering. 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 an 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.
In USA ABET which is an independent accreditation agency also accredits programs in mechanical engineering. A large number of employers choose to employ students from an accredited program. In the 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 mechanical 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 a minimum possible effect on the environment. Furthermore, in addition to the above-mentioned main mechanical engineering operations, a 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.
By using a thorough analysis and by using various models of mechanics, they outline modeling and finally they construct designs. By working in teams the mechanical engineers develop wide-ranging products that are benefiting people worldwide. For example, space vehicles or space shuttles which are used by NASA and other space agencies to explore the universe, aircraft of different shapes and sizes, turbines, pumps, automobiles, power plants, and factories and the machinery used within it to produce goods all are the work done by mechanical engineers. The amenities that we use every day for instance air condition, microwave, vehicles, communication devices, photo copier machines and much more, all are blessings of engineering
Most important works in mechanical engineering:
To know more What does a mechanical engineer do let see some important works of mechanical engineering. The horizon of mechanical engineering is growing at a rate which is faster than ever before. Plenty of research and important projects are currently going on in the field of mechanical engineering. The most important of them is:
Intelligent vehicle technologies consist of electro-mechanical, and electromagnetic devices. In order to operate the vehicle silicon micro machined parts are installed, which operates in combination with the computer – regulated devices. Although the idea of artificial intelligence is not new; there is a lot of research going on currently in mechanical engineering regarding these unmanned vehicles and number of vehicles were also launched by different automobile manufacturers recently.
Zero emission heat engines
Another accomplishment in the mechanical engineering field is its work on zero emission heat engines which is also known as liquid nitrogen vehicles. A zero emission heat engine is fueled by liquid nitrogen sometimes by electricity and water as well. Vehicles driven by liquid nitrogen have been displayed, but these vehicles are not used commercially like other conventional vehicles.
This is the most recent development in the field of mechanical engineering. The micro-electro-mechanical system is a complex system which runs on the technology of microscopic devices, more specifically those with relocating parts. It joins at the nano-scale into nanoelectromechanical systems (NEMS) and nanotechnology. Currently, many of mechanical engineering students study Micro-electro-mechanical systems as specialized courses during the degree programs of mechanical engineering.
Computational fluid dynamics:
Computational fluid dynamics (CFD) is another latest advancement in fluid mechanics which under the field of mechanical engineering. It is a branch of fluid mechanics that apply numerical analysis and algorithms in order to resolve and analyze difficulties that involve fluid flows.
Mechanical Engineer Salary
The median annual wage for mechanical engineers was $84,190 in May 2016. Mechanical engineer starting salary is $50,049 per year and it can go up to $98,961 per year depending upon qualification, experience, and type of job. The hourly income lies with in a range of $15.37 – $41.83. The average growth rate for mechanical engineering is 5% where as it is 7% for overall engineering.
Mechanical engineering is the field of engineering that is mostly related to the designing and manufacturing of mechanical systems. The field of mechanical engineering is not new to human being but this field gained attention and expanded rapidly during and after the industrial revolution. The recent advancements in the field are unmanned vehicles, zero emission heat engines, mechanical fluid dynamics, and others. The earnings of mechanical engineers differ from country to country and the demand for mechanical engineers is also growing worldwide. So this is the detail view on the topic of what do mechanical engineers do. If you have any question, please comment
