The field that we know today called engineering emerged from the remarkable advancement in constructing buildings in 2000 BC. Civil engineering developed until mechanical engineering was founded in Britain during the industrial revolution (Smith, 2017, October 5). At that time, mechanical engineering was derived from the inventions of steam engines and textile machines. Today, mechanical engineers design, develop, build, and test mechanical tools, engines, and machines. Mechanical engineers also diagnose and analyze problems of the machines to improve its performance or resistance to withstand environmental variables (Bureau of Labor Statistics, U.S. Department of Labor, 2016). In this report, we are examining different aspects of mechanical engineering.
Mechanical engineering (ME) is a broad engineering discipline that underlines broad research fields also. The major research areas for ME are energy, materials, robotics, biomedical engineering, and nanotechnology (University of Delaware, 2018). The research in energy investigates alternative energies (wind, geothermal, hydrogen) in respect to thermodynamics, heat transfer, and machine design. Advanced materials in mechanical engineering are being optimized to increase the durability, strength, and performance. Robotics is an emerging field that is constantly changing to meet the needs of humans to achieve tedious and difficult jobs. This field is one of the core fields of mechanical engineering that include robotic navigation, sensation, and response. Research within mechanical engineering also includes medicine and biological sciences to improve health and quality of life. Nanotechnology enabled the development of novel materials with a wide range of properties at the atomic and molecular scales.
Mechanical engineering encompasses broad research fields. Hence, the venues where research is conducted may vary upon the research field. Biomedical or biomechanical engineering research might be done in the clinical facilities, while the research on energy or materials might be done in the lab. Other types of research require collected data from the field, for example, one time in a research internship I took, I had to work outside the lab on a test engine. In addition, almost all the research that is done in ME depend on computers for predictive modeling, data processing, calculations, etc.
The type of courses and coursework in the major of mechanical engineering provides the fundamental knowledge in engineering science and applied mathematics. Students are exposed to the areas of solid mechanics, dynamics, materials, fluid mechanics, heat transfer, and thermodynamics (University of Delaware, 2018). Another type of courses is the engineering design where the student work to build different types of products such as machines, engines, etc.
The University of Delaware engineering program is one of the top-ranked programs in the United States. The Mechanical Engineering Department is located in Spencer Laboratory, within the College of Engineering cluster on the main campus of UD. The facility houses various research laboratories in the fields of mechanical engineering.
Since mechanical engineering is a broad field, engineers in this field are presented with a wide range of opportunities in industries such as aerospace, automotive, machines, bioengineering, and construction – just to name a few. In these different fields, mechanical engineers can perform fieldwork, research and development, or maintenance. As a student who is studying this major, I am drown to the field of aerospace. The aerospace industry was responsible for the many technological accomplishments that benefited humanity. Accomplishments were carried in the fields of computing, transportation, and robotics.
One of the issues that engineers in the space sector are facing is the hefty cost of working in this industry. Constructing a rocket has always been proven to be an expensive and time-consuming process. Once a rocket takes off, parts of it either stay up in space or fall away to earth and break apart in the ocean. The problem here is that this rocket, a costly investment, is thrown away in each new mission. When asked by a reporter about whether rockets are worth reusing, Elon Musk, the founder of SpaceX, replied by saying “Imagine you had $6 million in cash on a pallet flying through the air that’s just going to smash into the ocean. Would you try to recover that? Yes, you would,” (Simberg, 2012, February 12). Reusing rockets especially parts such as engines and propellant tanks will improve the economics of spaceflight, facilitating a new era of the space frontier.
There are many techniques for bringing back vehicles from space, such as using wings like the Space Shuttle, parachutes, or the most sophisticated technique of supersonic retropulsion. This method depends on the rocket’s propulsion system to manage acceleration, temperature, and pressure to make the rocket land vertically on the ground (Wall, 2017, April 10). Two aerospace companies are working on this technology, SpaceX and Blue Origin. SpaceX and Blue Origin initial tests in late 2015 have proven that this technology is successful (Bergstein, 2016). These companies were able to reuse rockets using supersonic retropulsion, achieving a milestone in the history of space.
