In this blog post, we’ll explore the role and future potential of mechanical engineering, which is utilized in a wide range of fields—from everyday life to automobiles, nuclear power plants, product design, and future convergence industries.
We use cars in many aspects of our daily lives—whether meeting friends, visiting relatives during holidays, or going on family trips. Because cars are such a familiar part of our lives, we often go about our daily routines without realizing just how important they are. While they have become so commonplace that nearly every household owns one, in the future, it will be difficult to continue relying on cars that run on crude oil—a resource with limited reserves that contributes to global warming and environmental pollution. What kind of cars will make our lives more convenient in the future? Currently, the most realistic alternative is the electric vehicle. This is because electricity is the most common power source; it is economical, very easy to charge, and safe due to its low risk of explosion. Electric vehicles are a field of interest and research in mechanical engineering. Engineers are developing electric vehicles through technologies that convert electrical energy into power to drive the wheels and operate the air conditioning, as well as technologies that minimize air resistance to improve fuel efficiency.
In the past, news reports widely covered South Korea’s decision to undertake the construction of overseas nuclear power plants. At first glance, one might wonder if mechanical engineering is even necessary for power plant construction. However, mechanical engineering plays a leading role in the construction of power plants. Designing plants to prevent the leakage of contaminants in the event of an earthquake and ensuring they generate electricity while maximizing energy utilization with minimal waste are all areas covered by mechanical engineering.
Furthermore, mechanical engineering plays a crucial role in the manufacture of various products. For example, when making a chair, no matter how beautiful or luxurious it may be, it cannot fulfill its intended purpose if it cannot support a person’s weight. Mechanical engineering determines the maximum weight a chair can bear and provides the solution for creating a chair that is both sturdy and aesthetically pleasing.
The Department of Mechanical and Aerospace Engineering at Seoul National University, which trains mechanical engineering students to play a pivotal role in various future industries, offers an undergraduate curriculum focused primarily on designing machines and objects and bringing them to fruition. The undergraduate program primarily involves studying the inherent properties of materials and, based on this knowledge, focuses on designing and manufacturing machines using computers. After exploring practical applications through the undergraduate program, students can choose to pursue further study in specific research areas or enter the workforce immediately to make their mark in various fields.
Mechanical engineering has established itself as a “jack-of-all-trades” in the industrial sector, providing essential technologies not only for the automotive and construction industries but for nearly every industrial field. The future of mechanical engineering is bright, as there are countless fields where mechanical engineering students can excel and many industries with great potential for growth. Unlike the past, when the field focused primarily on mechanical systems and the design of various objects, it is now broadening its horizons to pursue convergence with new fields.
In the field of artificial organs, the development of devices capable of treating human diseases—such as artificial retinas—could offer the gift of sight to those who have lost it. In the sports sector, the development of golf clubs that allow players to hit the ball farther, soccer cleats that efficiently transfer the force from the foot to kick the ball precisely in the desired direction, and high-performance swimsuits that cut through the water with minimal resistance will help athletes set new records. What new interdisciplinary fields in mechanical engineering will contribute to improving the quality of life for humanity?
