Why You Should Study Mechanical Engineering

A passion for science? Interested in creating inventions? These are characteristics that describe mechanical engineers! An engineer engages with anything that moves and aims to bring an idea to the marketplace.

Mechanical engineering is a diverse subject that derives its scope from the need to design and manufacture everything from small individual parts and devices (e.g., microscale sensors and inkjet printer nozzles) to large systems (e.g., spacecraft and machine tools). The role of a mechanical engineer is to take a product from an idea to the marketplace. In order to accomplish this, a broad range of skills are needed. The mechanical engineer needs to acquire particular skills and knowledge. He/she needs to understand the forces and the thermal environment that a product, its parts, or its subsystems will encounter; to design them for functionality, aesthetics, and the ability to withstand the forces and the thermal environment they will be subjected to; and to determine the best way to manufacture them and ensure they will operate without failure. Perhaps the one skill that is the mechanical engineer’s exclusive domain is the ability to analyze and design objects and systems with motion.


   What are the different disciplines of engineering?


Since these skills are required for virtually everything that is made, mechanical engineering is perhaps the broadest and most diverse of engineering disciplines. Mechanical engineers play a central role in industries such as

  • Automotive (from the car chassis to its every subsystem—engine, transmission, sensors)
  • Aerospace (airplanes, aircraft engines, control systems for airplanes and spacecraft)
  • Biotechnology (implants, prosthetic devices, fluidic systems for pharmaceutical industries)
  • Computers and electronics (disk drives, printers, cooling systems, semiconductor tools);
  • Microelectromechanical systems, or MEMS (sensors, actuators, micropower generation)
  • Energy conversion (gas turbines, wind turbines, solar energy, fuel cells)
  • Environmental control (HVAC, air-conditioning, refrigeration, compressors)
  • Automation (robots, data and image acquisition, recognition, control)
  • Manufacturing (machining, machine tools, prototyping, microfabrication)


   What do mechanical engineers learn during their studies?

To put it simply, mechanical engineering deals with anything that moves, including the human body, a very complex machine. Mechanical engineers learn about materials, solid and fluid mechanics, thermodynamics, heat transfer, control, instrumentation, design, and manufacturing to understand mechanical systems. Specialized mechanical engineering subjects include biomechanics, cartilage-tissue engineering, energy conversion, laser-assisted materials processing, combustion, MEMS, microfluidic devices, fracture mechanics, nanomechanics, mechanisms, micropower generation, tribology (friction and wear), and vibrations. The American Society of Mechanical Engineers (ASME) currently lists 37 technical divisions, from advanced energy systems and aerospace engineering to solid-waste engineering and textile engineering.


   What kind of career options do mechanical engineers have?

The scope of the mechanical engineering discipline allows students a variety of career options beyond some of the industries listed above. Regardless of the particular path they envision for themselves after they graduate, their education will have provided them with the creative thinking that allows them to design an exciting product or system, the analytical tools to achieve their design goals, the ability to overcome all constraints, and the teamwork needed to design, market, and produce a system. These valuable skills could also launch a career in medicine, law, consulting, management, banking, finance, and so on.


Stepping Stone to an International Career

Studying at the CBS was my stepping stone towards an international and diverse career start. Being immersed in a multi-national study environment has nurtured my passion about connecting people with different backgrounds in order to form a strong team. Besides the valuable set of soft skills with regard to leadership, I truly learned to dive deep into technical topics and develop my own approach to engineering. Currently, I am an active trainee for Daimler’s top talent program called “CAReer”. My projects are spread around the globe and took place on three continents. My company offers exactly the balance between international opportunities and high-level engineering which fascinated me about the CBS. All in all, I can only recommend starting your academic path in Karlsruhe as it equipped me with all skills necessary to succeed in my professional life.
