In This Course You Will Study The role of engineers and engineering technologists Force, motion, energy, fuels, and engines Logic and computing systems The elements of engineering design Engineering economics And much, much more! Exploring Engineering

What Is Engineering? Engineers can be classified according to the kind of work they do—administration, construction, consulting, design, development, teaching, planning, production, research, sales, service, and test engineers. Because engineering deals with the world around us, the number of engineering disciplines is very large. The table below lists some of the many engineering fields. Aerospace Ceramic Electrical Mechanical Petroleum Agricultural Chemical Environmental Metallurgical Sanitary Architectural Civil Geological Mining Systems Automotive Computer Manufacturing Nuclear Textile Biomedical Ecological Marine Ocean Transportation Exploring Engineering

What Is Engineering Technology? Engineering technology is the profession in which a knowledge of mathematics and natural sciences gained by higher education, experience, and practice is devoted primarily to the implementation and extension of existing technology for the benefit of humanity. Engineering technologists work closely with engineers in coordinating people, material, and machinery to achieve the specific goals of a particular project. The engineering technologist is often responsible for design and development. Exploring Engineering

st What Makes A “GOOD” 21 Century Engineer? The 21 st century will be characterized by the convergence of many technologies and engineering systems. The products of today and tomorrow will be “smarter” in which computers, sensors, controls, modern alloys, and plastics are as important as continuing expertise in the traditional engineering disciplines.

Personal Ethics Personal ethics are the standards of human behavior that individuals of different cultures have constructed to make moral judgments about personal or group situations. Naturally, they vary over time and from culture to culture, resulting in conflict when what is acceptable in one culture is not in another. For example, the notion of privacy in U. S. culture is very strong, and a desk is considered an extension of that privacy, whereas in another culture, such as Japan, office space is open and one’s desk would be considered public domain.

Professional Ethics Having a code of ethics enables an engineer to resist the pressure to produce substandard work by saying, “As a professional, I cannot ethically put business concerns ahead of professional ethics. ” It also enables the engineer to similarly resist pressure to allow concerns such as personal desires, greed, ideology, religion, or politics to override professional ethics. As members of this profession, engineers are expected to exhibit the highest standards of honesty and integrity. Engineers perform under a standard of professional behavior that requires adherence to the highest principles of ethical conduct. Exploring Engineering

National Society of Professional Engineers Code of Ethics Fundamental canons Engineers, in the fulfillment of their professional duties, shall • Hold paramount the safety, health, and welfare of the public. • Perform services only in areas of their competence. • Issue public statements only in an objective and truthful manner. • Act for each employer or client as faithful agents or trustees. • Avoid deceptive acts. • Conduct themselves honorably, responsibly, ethically, and lawfully so as to enhance the honor, reputation, and usefulness of the profession.

Engineering Design Is: Synthesis – putting things together Analysis – taking things apart Exploring Engineering

Example - Buying a Car A car salesperson might say: a) “This car was driven by an older person who never exceeded the speed limit. ” and b) “It has great power, excellent fuel efficiency, and low pollution. ” What would an engineer say to part a)? Exploring Engineering

Design Criteria For part a) an engineer might say: “It was driven by a human about 1. 7 meters high and 2 billion seconds old who never drove it faster than about 70 meters per second. ” Variable Height Age Speed Unit meters seconds m/s Exploring Engineering Number 1. 7 2 x 109 70

Design Criteria In part b) when the salesperson says “It has great power, excellent fuel efficiency, and low pollution. ” An engineer might say: “(You fill in this part and define the variables, units, and numerical values)” Variable Unit Exploring Engineering Number
