Engineering While …… Scientists ask how? Mathematicians ask how much? Physicists ask why? Engineers ask “why not?” and they seek to change the world. Wright Brothers, 1900 Wright Brothers, later that year… Wright Brothers, 1903 Modern Aviation, 2003 Concord travels at 1,330 mph Rochester to Buffalo in 2.7 minutes Changing the World Then….. 1903 Now…… 2003 Engineering Science Physics Math Mechanical Engineers Study the mechanics and dynamics of systems. Design new systems to to accomplish specific tasks. 735,000 pounds Mechanical Engineers Concerned with the physics of energy loss and how to minimize friction. Mechanical Engineers Calculation and measurement of thrust and minimizing energy usage. 63,000 pounds of thrust Mechanical Engineers Concord grows by 9.44 inches in flight due to structural deformations Concerned with structural integrity – how strong??? Electrical Engineers Everything related to electronic devices and systems and the use of electricity. Electrical Engineers Electronics are used to control the airplane and monitor system performance and status, communicate with the control tower. Electrical Engineers Computer Engineering - design the software and hardware for the computer. Microelectronic Engineering - everything on the small scale - design and fabrication of computer chips. Civil Engineers Plan, design, and supervise construction of facilities and large structures. Civil Engineers Projects involve: bridges and highways subways high-rise buildings shopping malls airports ground water supply water treatment centers Civil Engineers Concerned with: structural design environment conditions foundation and soil types water run off noise abatement snow and ice removal Industrial Engineers Price of Boeing 747 is $183,000,000 Industrial Engineers Organizers: people, information, materials and machines involved in the production process. Industrial Engineers Concerned with plant design and management, quality control, and human factors of engineering. Chemical Engineers Fuel sources, combustion, environmental impacts Other projects: beauty products, medicine, new materials (lighter, stronger, cheaper –plastics), recycling, pollution monitoring and control, waste water management Engineering….. Civil, Mechanical, Electrical, Industrial Chemical Other specialties within the main 5: Manufacturing Microelectronic Computer Materials Biomedical Environmental Naval Aerospace Automotive Many more…….. Engineering….. Airplanes, Cars, Buildings, Bridges, Medical Tools, Artificial Organs, Robots, Nuclear Power Plants, Ski’s and other Sports Equipment, Refrigerators, CD Players, Children’s Toys, Solar Power Plants, Assistive devices for elderly and handicapped…. Is Engineering for you? • Do you enjoy knowing how things work? • Do you ever think of new or better ways to do things? • Do you get good grades in math and science? • If you get a gift that says “assembly required”, do you put it together yourself? • Do you like to work with computers and play video games? • Do you like to do mazes and jigsaw puzzles? • Do you usually make sound decisions and do people trust your judgment? • Can you express yourself easily and clearly? • Do you work well with others? • Do you ask yourself “why not? You too can change the world…..
