CHAPTERS 2&3 Engineering Majors ELEC 104, Fall 2010Dr. McKinney
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”
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”
What do Engineers do? • Three variables • Discipline/Major • Position/Function • Industry
Engineering Functions Design, Development, Research, Test, Analysis, Production, Sales, Technical Support • Get into eight groups • Develop 2 bullet points describing the engineering function you have been assigned
Design Engineer • Produce dimensions and specification for a product to ensure is works with existing systems and products • Redesign and modify parts to reduce production time and costs and to redesign products that have not lived up to expectations
Development Engineer • Test new products and see if they will work in a large scale production • Take knowledge acquired from researchers to use on specific products
Research Engineer • Explore fundamental principles through the use of experiments in order to overcome technical barriers • In order to save time they use computational techniques to solve complex problems
Test Engineer • Develop data acquisition and instrumentation systems and methods to verify integrity, reliability and quality of products before they are introduced to the public • Must have a wide range of technical and problem solving skills
Analysis Engineer • Specialize in one particular area and provide technical expertise in that area • Serve as an interface between the test engineers and design engineers to determine the pertinent information needed by both groups
Production Engineer • Develops processes to manufacture a product by taking raw materials forming them into finished pieces considering manufacturing concerns such as cost, risk, and quality. • Keep track of equipment in the plant as well as maintain a safe and reliable workplace.
Sales Engineer • Answer customer concerns and guide customer through the appropriate product selection process • Identify applications and other products for the customers to use
Technical Support Engineer • Support and assist the customer to ensure that they can use the product in the most efficient way • Know enough about the problem and the product to be able to find the necessary information to solve nearly any problem
Engineering Majors Biomedical, Electrical, Computer, Chemical, Civil & Environmental, Materials, Aerospace, Mechanical • Rearrange into eight different groups • Develop 2 bullet points describing the engineering major you have been assigned
Biomedical • Responsible for designing medical equipment to make medical procedures go more smoothly • Work with any part of the biological systems • Divided into medical engineering, bio-engineering and clinical engineering
Electrical • Apply principles of electricity to solve problems and develop new technologies • Broad field which ranges from nanotechnology to power generation
Computer • Design and develop hardware for computer systems • Optimize HW/SW interfaces, working alongside computer scientists
Chemical • Uses chemical properties and physics, applying them in design and developmental processes to mass produce products in society • Work with various materials such as plastics, oil, and natural gasses to make various products ranging from circuit boards to artificial kidneys
Civil & Environmental • Environmental engineers job is to prevent, improve and maintain the environment in the wake of industrial activity • A Civil engineer’s primary function is to build and maintain structures to keep the economy stable • Main fields are: structural, architectural, transportation, water resources, urban planning, and construction
Materials • Material engineers innovate current materials and develop new materials • Test and conduct experiments on materials to ensure their performances meet expectations
Aerospace • Design and build machines to fly within (and outside of) the Earth’s atmosphere • In addition to designing machines, they must take the physiological limitations of human beings into account • Main fields include: propulsion and energy, space and missile systems, aerospace sciences, and structure and design testing
Mechanical • Divided into two main categories: • Design and controls – deal with the design and testing of engineering components • Thermal Sciences – deal with heat transfer and also predict and study the temperatures of components in environments • Broad field ranging from fluid engineering to nuclear engineering
Homework (due in one week) Pick three blocks in the cube (Figure 2-1) and write a job description for that engineer. None of your blocks can haveany similar variables.
Profiles in Engineering • Combine groups into four groups • Each group take one of the specified profiled engineers • Study the bio in the text • Present this person to the group • What do they do? • Where do they fit into the “cube”? • Do they seem to enjoy engineering? • Does their life seem to be in balance?
Homework (due in one week) • Imagine yourself 10 years from now and type up a one page profile in the same format given in the book.
