Major Engineering Disciplines Aerospace Engineering Agricultural Engineering Chemical Engineering Civil Engineering Computer Engineering Electrical Engineering Industrial Engineering Mechanical Engineering Dr. Vlasov 7
Engineers and Scientists Scientists seek technical answers to understand natural phenomenon Engineers study technical problems with a practical application always in mind For example: Scientists study atomic structure to understand the nature of matter; engineers study atomic structure to make smaller and faster microchips Dr. Vlasov 8
The Engineer and the Engineering Technologist Main difference between the two is: Engineers design and manufacture machines and systems, while engineering technologists have the technical know-how to use and install the machines properly An example: The technologist identifies the equipment necessary to assemble a new CD player; the engineer designs said CD player Dr. Vlasov 9
Engineering Functions: 1. Research 2. Development 3. Testing 4. Design 5. Analysis 6. Systems 7. Manufacturing & Construction 8. Operations & Maintenance 9. Technical Support 10. Customer Support 11. Sales 12. Consulting Dr. Vlasov 10
Engineering Functions: Research Research engineers are knowledgeable in principles of chemistry, biology, physics, and mathematics Computer know-how is also recommended A Masters Degree is almost always required, and a Ph. D is often strongly recommended Dr. Vlasov 11
Engineering Functions: Development Development engineers bridge the gap between the laboratory and the production facility They also identify problems in a potential product An example is the development of concept cars for companies like Ford and GM Dr. Vlasov 12
Engineering Functions: Testing Testing engineers are responsible for testing the durability and reliability of a product, making sure that it performs how it is supposed to, every time. T.E.s simulate instances and environments in which a product would be used. Crash testing of a vehicle to observe effects of an air bag and crumple zone are examples of a testing engineer s duties. Dr. Vlasov 13
Engineering Functions: Design Design aspect is where the largest number of engineers are employed. Design engineers often work on components of a product, providing all the necessary specifics needed to successfully manufacture the product. Design engineers regularly use computer design software as well as computer aided drafting software in their jobs. Dr. Vlasov 14
Engineering Functions: Design (continued) Design engineers must also verify that the part meets reliability and safety standards required for the product A concern always on the mind of design engineers is how to keep the development of a part cost effective, which is taken into account during a design process Dr. Vlasov 15
Engineering Functions: Analysis Analysis engineers use computational tools and mathematic models to enrich the work of design and research engineers. Analysis engineers typically have a mastery of: heat transfer, fluid flow, vibrations, dynamics, acoustics, and many other system characteristics. Dr. Vlasov 16
