How to choose a project topic?

Always select a project that adds value, and never pick one that someone gave you or suggested to you blindly. Don’t even take your advisor’s word blindly. Instead, actually sit down and analyse how the project will help you become a better engineer.

Choose a project that addresses a common problem, and solves it. Try to look for common causes or issues faced by people, and try to find answers to those issues.

Focus on your area of interest and choose a project that will help you explore that field properly. Read up on the basics, understand what the project will require you to and finalize on it, only if you feel like it is something you would like to take up in the future.

Look for innovative solutions, but make sure you stay practical and focused. Sometimes, people come up with the most complicated solutions to the easiest of problems. Not only do these projects require very complex engineering, but it is also very often, too expensive. Scale your problem down, and find the simplest, and most efficient solution for it.

Be extremely practical when you set your goals. As students, you have a lot of limitations, such as capital, tools, expertise and even time. Instead of trying to move mountains, try instead to scale hills, but do so effectively and efficiently.

Be creative and try to analyze the problem from different angles until you fall upon one that just clicks. Identify different combinations possible and go for the one that requires minimal cost and resources.

Just finding an innovative solution is not enough, you all also need to be present it well. So, make sure you present the final report in an appealing and formal manner. Prepare a high-impact presentation, and create an information-rich project summary and description. Follow this up with a comprehensive summary, and submit everything on time.

Scope of Mechanical Engineering

While core mechanical principles, such as thermodynamics, turbomachines, fluid mechanics, and machine design are still useful and very much valid, new technologies such as composites, mechatronics, and nanotechnology are also gaining momentum. Hence, mechanical engineers will see more growth in engineering services fields, while continuing to play an important role in various manufacturing industries, such as the automotive industry. Since such engineers work on the newest industry trends, such as automation and robotics, the field undergoes upheavals every decade or so. The field of alternative energy production and nanotechnology will also offer new opportunities and mechanical design production will help in popularizing ideas and making these ideas a reality.

Duties of a Mechanical Engineers

  1. Analyze problems and find solutions for them
  2. Use basic mechanical principles such as thermal engineering and basic mechanics to solve everyday design problems
  3. Design and redesign mechanical devices and subsystems
  4. Use analysis to study and improve the computer-aided design
  5. Investigate equipment failures and improve device quality
  6. Diagnose faulty operation recommend remedies
  7. Develop and test prototypes
  8. Analyze test results and redesign as and when required
  9. Oversee the manufacturing process

Artificial intelligence, biomechatronics, and nanotechnology are some of the upcoming fields which will have a great impact on mechanical engineering. As the transportation sector generates the largest amount of greenhouse gases, environmentalists and other such agencies are pushing for a move towards electric vehicles. Furthermore, the pressure has never been higher with regards to shifting to more eco-friendly sources of power. Both these shifts will require the help and effort of mechanical and energy engineers. The automotive industry is one of the biggest employers of mechanical engineers and with the need for electric cars so high, the future looks good for such engineers. Design engineers will be needed to replace traditional internal combustion engines with batteries, and large-scale production factories for such vehicles will need the supervision of mechanical and production engineers.

Also, as the demand grows such factories will have to get automated, and in such cases as well, it is mechanical engineers who will have to help with the shift. Nanotechnology is another rapidly growing field and one that offers abundant opportunities to mechanical engineers. The creation of stronger composites, development of renewable energy storage systems and the development of advanced biomedical devices will all happen with the help of mechanical engineers. Manufacturing is an ever-evolving field which changes regularly due to the influx of new and innovative technologies. While new technologies have changed the engineering landscape, the future looks bright for mechanical engineering. However, such engineers will have to make sure that they keep up with current and future advancements to stay relevant and avoid being left behind.

How to reduce the cost of the project?

How do we make it cheaper? This is one question that every student asks while working on his or her student project! So, how do you answer this very familiar question?

Understand that there is beauty in simplicity. Therefore, as far as possible, while going through solutions, go for something that is simple and effective to reduce unnecessary costs.

Make sure you really put a lot of effort into your planning stage. While it may be tempting to rush through and start, this leads to higher overhead costs, when you do end up making mistakes.

While having a consistent development plan is important, look into the new insights you get and remember to re-adjust your plan accordingly.

Try to repurpose old designs whenever you can, instead of starting from scratch every time.

Though too many cooks spoil the broth, whenever possible try to collaborate as this helps you troubleshoot problems faster and more efficiently. When you have been staring too long at something, it is too difficult to find solutions. Instead, pass the problem over to someone else to get a fresh perspective.

Reduce prototyping and instead rely on simulations as much as you can.

How to Become a Mechanical Engineer?


While in school, students who are interested in becoming Mechanical engineers should focus on industries, production and manufacturing. Try visiting a plant near your home to understand your future work environment. Students should develop an interest in problem-solving, and should try to understand how various devices and machines work. Further, they must develop their skills in math and physics.


After their 12th, they should attempt the engineering entrance exam, and try to score well so that they get into reputed engineering colleges for their bachelors. Most mechanical engineering programs include courses in mathematics, physical sciences, and design. The courses will have an even balance of theory and practical’s, with a lot of importance given to workshops and laps. Also, such courses will emphasize internships to help students prepare for work in industries.
