Aerospace Engineering: This field of engineering focuses on the desgin and the development of aircraft production and testing as well as rockets, missiles, spacecrafts and other systems that operate beyond the earth's atmosphere. This field requires a lot of knowledge in different disciplines such as structural design, aerodynamics, thermodynamics, materials, etc. Aerospace engineering in most companies is mostly performed in teams focusing on different areas as well as technology and economic feasibility.
Chemical Engineering: This field of engineering deals with manufactruing prodcuts through chemical processes as well as chemical production. Chemical engineers are also in charge of designing equipment and systems to refine and process raw materials and mixing them with chemcials to make products. Chemcial engineering is based on chemistry, biology, physics and math and engineers apply yhese areas to solving problems in their fields such as production of fuel, drugs and food.
Mechanical Engineering: This field is a very wide and versatile one. It deals mainly with the design, analysis, manufacturing, and the maintenance of mechanical systems. Those who specialize in this field are knowledgeable in thermodynamics, dynamics, mechanics, materials science, structural analysis, and electricity. They oversee a wide array of technologies, from manufacturing plants and industrial equipment to transportation systems and medical devices.
Industrial Engineering: This type of engineering is one of optimization. It specializes in the streamlining of industrial processes, systems, and organizations; whether that include information, people, money and equipment. Key areas of understanding include social, mathematical, and physical sciences as well as engineering analysis and design. These engineers then use these core principles to improve logistical coordination as well as the efficiency and refinement of both physical and social systems.
