Engineering is an extremely broad field divided into three primary disciplines: Mechanical, Electrical, Civil, and Computer engineering. This article aims to discuss mechanical engineering as a discipline and dive deeper into answering a common question about mechanical engineering. This article will also explain why other engineering disciplines like Petroleum, Nuclear, Material, Chemical engineering, etc., are not considered as main engineering disciplines.
What is a Mechanical Engineering?
Mechanical engineering is a branch of engineering that covers design, construction, operation, maintenance, and machinery utilization through the application of physics, mathematics, materials science, and engineering principles to provide a service and improve quality of life. This field of engineering came into existence after the industrial revolution that took place in the 18th century.
Mechanical engineering is considered the most diverse as compared to the rest of the engineering disciplines. It plays a vital role in the transportation industry (automotive, aerospace), health industry (biotechnology, prosthetics), electronics industry (computers, microchips, disk drives, printers, semiconductors), and manufacturing industry (robots, automation machines, wind turbines, fuel cells, and compressors).
Mechanical engineering is concerned with designing, building, running, and operating the different devices, tools, and machinery used in these industries from start to finish. Mechanical engineering products can range in size from small machinery such as Nano-robots and miniature connectors to huge ones such as airplanes, rockets, and power plants. As you might have figured already, Mechanical Engineering overlaps with multiple engineering fields such as manufacturing, metallurgical, civil, chemical, electrical, aerospace engineering, etc.
What does a Mechanical Engineer do?
Mechanical Engineers identify problems, analyze them, devise means, and utilize mechanical devices that might help solve the problem. These problems can be design problems that require redesigning, prototype testing that needs to be approved and feasible for implementation, and manufacturing or industrial processes alterations that would improve quality and efficiency.
In order to achieve these tasks and handle different problems, certain tools are usually used by mechanical engineers, such as 3D design software, simulation software, mathematical modeling software, and different software used for different purposes.
For example, let’s say that you are a mechanical engineer working in the field of transportation. You will be responsible for improving the engine’s efficiency of the vehicles used. This can be achieved by optimizing the vehicle’s fuel ignition, transmission, suspension, aerodynamics, etc. You can also be a mechanical engineer working in the field of heating and cooling systems.

Many, then, become managers and administrators for companies and startups. In order to be able to teach at universities as a professor with an engineering background, you have to obtain a PhD. Degree in a specific field and then apply for faculty positions at universities.
What makes an excellent mechanical engineer?
Mechanical engineers enjoy tackling different problems and devising innovative solutions that would help improve a process or machine’s efficiency. They are interested in the latest technological innovations, and they are strong analytical thinkers. They should possess good communication skills to be able to explain and clarify the functionality of the process or machine to the client, who is usually not aware of the mechanical engineering terminology.
Mechanical engineering also involves lots of teamwork and brainstorming sessions that require collaboration between different people. Hence, leadership and teamwork skills are vital for a mechanical engineer. Successful mechanical engineers need to possess a specific list of necessary qualities to excel in their careers. This list includes, but is not limited to, problem-solving, analytical thinking, creativity, proactivity, meticulosity, leadership, teamwork, communication, math, and computer skills, efficient work under pressure, troubleshooting, and much more.
Advice for mechanical engineering students?
Like in any other field, gaining work experience and good academic success is the key to achieving a competitive job offering. Therefore, it is recommended that throughout the academic course of studies, you focus on getting good knowledge as we as good grades.
During the years of study, it is highly recommended that you gain real work experience during the summer. So, is that it?! Good grades and work experience! No, it would be best if you also stay updated and aware of the latest technological changes and breakthroughs. One more thing, it is highly recommended that you build network friends and employers during your studies and internships to help you land a competitive and exciting job quickly after graduation. It is all about networks, reputation, and previous work experience.
If you successfully achieved those main factors during your studies, you will easily find a competitive job offer with a relatively high salary.

What is it like being a mechanical engineer?
This will vary depending on the field you are working in. Nowadays, computers and software have changed the way problems are calculated and solved, making them more accurate and less time-consuming. However, mechanical engineers still need to be aware of the mathematics and engineering principles upon which the software is built. In the end, the software is just a tool that can output wrong outputs if used wrongly.
Mechanical engineers do not always handle the technical details and spend time working on machines holding a calculator in hand. As a mechanical engineer, you can manage businesses, handle contracts, design machinery, solve issues and problems, invent novel techniques, etc. It is an extremely broad field that gives you the potential to work in various areas and be successful because of your analytical and problem-solving skills.
A day in the life of a mechanical engineer can hence be different from one mechanical engineer to another.

In conclusion, mechanical engineering is a challenging career choice. However, if you have the passion and characteristics that shape a mechanical engineer, then you should go for it. As a mechanical engineer, you will have the capability to understand and perform various tasks, ranging from highly technical assignments such as designing and manufacturing Nanorobots to project management and handling clients’ requests.
It is a story of love and hate. You know that you enjoy exploring the exciting and innovative ideas behind almost everything we use in our daily lives, making you fall in love with it and have a passion for inventing and implementing something yourself that would affect lives and benefit people. However, on the other hand, you are usually not paid enough. It requires lots of time and dedication and effort, and hard studying that might drain your energy and leave you with less social life than other disciplines. However, I need to mention that it is always up to you to balance your social life and career.
Being a mechanical engineer can be your life and source of happiness and enjoyment. You also do not need to become the best mechanical engineer that ever existed; you can be a good mechanical engineer who balances his leisure time and work and achieves his inner happiness. You will spend most of your life and time working, almost equal to the time you spend sleeping, so you might as well do something that you would enjoy and pushes you to become the best version of yourself.
