Mechanical engineering is probably the oldest and broadest branch of engineering. It deals with the analysis, design, manufacturing, maintenance, of the various mechanical systems based on the principles of physics and materials science. It often involves study of heat and its applications in design, production, and operations of machine and tools.
The core concepts of mechanics, kinematics, thermodynamics, materials science, and structural analysis are important in becoming of a mechanical engineer. Mechanical engineer puts together the concepts and principles of these fields in building or maintenance of sound machines and tools.
A lot of business and fields depend on mechanical engineering for one or more operations, and therefore the applications of the field are very broad. For example, there is application of mechanical engineering in construction, in vehicles, in aircraft and spacecraft, and almost every disciple. Even in homes, there is application of mechanical engineering where many machines and tools are there. Hence one can’t isolate this field due to their multi-fold applications. A mechanical engineer needs to understand various disciplines of physics and how they work simultaneously to understand the problems and devise solutions for the same, be it in any field.
Mechanical engineering is a big employment sector due to its applications in almost every field. Therefore, there are plenty of jobs around the world. The growth in this sector is slower than other emerging fields because of it being an old field; however for those who’re interesting in the subjects, there are enough jobs. It all depends on one’s interest in the field because often it may be laborious and only interest factor can bail a person out of some situations.
The education required for the field is mostly a four year bachelors of engineering which may be called by different names at different places. It is followed by an internship. If interested, candidates may take up masters of engineering also which usually provides better and higher-paying jobs. However, one may have to take a couple of years more of tough education. A doctorate may be taken. Polytechnic courses are also available which are often diplomas and are highly job specific courses for immediate employment basis.
Mechanical engineering may be widespread, but a mechanical engineer often knows more than one fields of study and knows how to apply the combined concepts in various fields. A candidate for mechanical engineering must have high aptitude and understanding for physics and its various disciplines to sustain a career in the field.
