Mechanical engineering comprises the design and analysis of heat and mechanical power for the operation of machines and mechanical systems.
Engineering is the discipline and profession that applies scientific theories, mathematical methods, and empirical evidence to design, create, and analyze technological solutions cognizant of safety, human factors, physical laws, regulations, practicality, and cost. In the contemporary era, engineering is generally considered to consist of the major primary branches of chemical engineering, civil engineering, electrical engineering, and mechanical engineering.  There are numerous other engineering subdisciplines and interdisciplinary subjects that may or may not be part of these major engineering branches.
Engineers apply scientific principles to design or develop structures, equipment, or processes. Engineering encompasses several disciplines. Traditionally, the main branches of engineering are chemical engineering, civil engineering, electrical engineering, and mechanical engineering, but there are many other areas of specialization.
Here is a summary of the main branches of engineering:
- You’re interested in an engineering career related to computers – for example as a software developer or computer engineer.
- You’re interested in mathematics, science and computers, and want to learn more about how computers operate at a physical level.
- You want to produce new products and systems based on the technological advances of computer scientists.
Engineering is an extensive subject, and with so many types of engineering to choose from, it can be difficult to narrow down which one is for you. To help you to decide, you should try and identify what you’re passionate about. What gets you excited, and what do you spend your free time on? All types of engineering include some form of problem-solving (and generally focus on making life easier), but what engineering-related solution gives you the biggest buzz? If you choose a subject you’re naturally interested in, you’ll find it easier to stay motivated during your course and stay involved with the subject whilst pursuing an engineering career.
Biotechnology is the actions that are used to make or modify the products of living organisms in order to improve plants or animals or to develop useful microorganisms. It is the application of advanced biological techniques in the manufacture of industrial products, including the production of antibiotics, insulin, and interferon, or for environmental management, such as waste recycling. It focuses to the use of engineering methods, instrumentation, and technology to solve medical problems, including the manufacture of artificial limbs and organs, the design and construction of hospitals, the development of community health programs, and the study of ways to control the environment.
Safety engineering concerns the design of a machine or facility and evaluate the procedures to ensure safe operation and minimize accidents.
Read through the following information and highlight any areas you find interesting. then ask you careers counselors for more information on each specific area of interest.
Resource engineering is concerned with the development and efficient use of natural resources and the management of environment in rural areas. It includes the development, conservation and control of water resources, soil conservation and recovery of degraded land, catchment and land management, assignment and control of water pollution from agricultural and mining industries. Particular roles of resource engineers include estimation of water yields from catchments, flood analysis, design and construction of drainage and irrigation systems sympathetic to the environment. Resource engineers are employed by government management agencies and local government bodies, consulting engineers, the mining and forest industries and civil engineering construction companies.
