Mechanical Engineering is the mother of all engineering fields
Mechanical engineering affects all facets of human life to improve and make the world a better place to live in. They are the ones who does confront with the greatest of challenges that of energy, safe water and the transportation. They are the ones who design the ultra sophisticated tiny devices that navigate the human body to investigate diseases saving life. It is through their hard work we are able to enjoy our everyday life, from mobiles to iPods to computers to that of our favorite video game. In fact, virtually everything you are acquainted with during the course of the day, there is mechanical engineering that have something to do with it for to help improve our existence.
Mechanical engineers do create and develop the mechanical systems for all of humankind. They are concerned with the principles of force and motion to design, manufacture and for seamless operational processes for the advancement of the world enhancing the safety measures and economic vitality. Each and every sector does require mechanical engineers from thermal power station or the air conditioning industry or gas turbines industry and also in other industries.
Can I become a mechanical engineer?
As an aspiring mechanical engineer you should have a solid foundation in mathematics and science. The capacity to solve problems coupled with the learning and knowledge of the mechanical design for to identify the various problems and come up with effective solutions to address those. A good communicator and a good listener further help to make a mark in your profession as your work involves interactions and an amalgamation with the other engineers to come out with a better solution for the client. The sheer behavior of curiosity along with a sense of creativity work drastically well for a mechanical engineering aspirant. The ability to merge applying the concept of engineering science and the technology for designing for the production of various goods is an ultimate goal for a mechanical engineer. Balancing both ends the ticket towards success.
For career and job opportunities you can choose from an end number of industries
There are a lot of job prospects for a mechanical engineer pass out. They are required for designing, the manufacturing, the installation of various parts and the operating systems that are needed in innumerable industries. Opportunities exist both in the private and the public sector. In a government sector, fresher are recruited as a junior engineer and goes up the ladder as a Assistant engineer to a assistant executive engineer to a executive engineer to a superintendent engineer and so forth. For a mechanical engineer graduate employment offers do come from different industries like automobiles, aeronautical industries, space research centers, steel plants , oil exploration and refining and also bio-mechanical.
The remuneration that you get is ample and ranges between Rs.10,000- Rs.25,000 on a monthly basis. Those who have extended their qualification to post graduation are offered a bigger salary scale. You can also expect an annual pay package of 40 lac pa in the later part of your career depending on the experience and the skills you attain.
