What is an Engineer?

1. What is an Engineer? Engineers do more than study theory, they use the laws of math, physics, chemistry, biology, and other sciences as tool to make new products and processes that benefit mankind.

2. Chapter 1: The History of EngineeringSection 1.1 - Introduction ABET* Definition of Engineering: The profession in which knowledge of the mathematical and natural sciences, gained by study, experience, and practice, is applied with judgment to develop ways to use, economically, the materials and forces of nature for the benefit of mankind. *ABET: Accreditation Board for Engineering and Technology

3. Chapter 1: The History of EngineeringSection 1.1 - Introduction Key Items within this Definition of Engineering: • Knowledge in Math and Sciences very important • Knowledge gained from various sources: study, experience and practice • Engineering is an applied art and practice • Engineering seeks economical solutions • Engineering serves to benefit mankind

4. Engineering Majors • The big four • Civil EngineersDesign our infrastructure – bridges, roads, wastewater treatment, traffic control, buildings • Mechanical EngineersDesign our mechanical systems – automobiles, robotics, heating and cooling, industrial machinery, buildings • Chemical EngineeringDesign our chemical processes – plastics, material science, nanotechnology, pharmaceuticals • Electrical EngineeringDesign our electrical systems – power delivery, communications, computers, robotics

6. Chapter 2: Engineering MajorsSection 2.4 – Emerging Fields Engineering Fields are constantly changing Some emerging Fields include: • Smart Building Technology • Nanotechnology • Information Technology

7. Chapter 2: Engineering MajorsSection 2.1 - Introduction Engineers… • Invent • Design • Develop • Manufacture • Test • Sell • Service Products and Services which improve the lives of people.

8. Chapter 2: Engineering MajorsSection 2.2 – Engineering Functions A Function describes what an engineer might do in a job environment. Functions include: • Research and Development (“R and D”) • Test • Design • Teaching • Sales

9. What do Engineers do? • Three variables • Discipline/Major • Position/Function • Industry

10. Electrical Engineers • Electrical Engineers work with electrons… • some work with LOTS of electrons to distribute and convert energy between various forms, and... • others work with fewer electrons to gather, store, process transport, and process information. • Seven main areas of EE: Communications systems, computer systems, control systems, electromagnetics, electronics, power systems, and signal processing

11. Engineering Quotes • “Scientists investigate that which already is; Engineers create that which never has been.” Theodore von Karman • “Engineering is the application of science to the common purpose of life”Count Rumford • “To define it rudely but not inaptly, engineering is the art of doing that well with one dollar which any bungler can do with two.“Arthur M. Wellington

12. Steps to become an engineer • BSEE - Complete Bachelor’s of Science degree in electrical engineering; more than 200 accredited programs http://www.abet.org/ • FE Exam - Pass Fundamentals of Engineering Examination; 8 hr. exam typically taken during senior year. • Experience - Work on engineering projects under the direction of a registered Professional Engineering for 4-years, or 3-years with a MS degree in a specialty area. • PE Exam - Pass Professional Engineer’s Examination; 8 hr. exam covering design, engineering analysis and ethics. • PDH’s - Maintain engineering competency through yearly professional development and life long learning activities

13. Professional Ethics Code of Ethics a. using their knowledge and skill for the enhancement of human welfare and the environment; b. being honest and impartial and serving with fidelity the public, their employers and clients; c.  striving to increase the competence and prestige of the engineering profession; and   d.  supporting the professional and technical societies of their disciplines. Fundamental Principles: Engineers uphold and advance the integrity, honor and dignity of the engineering profession by: http://www.asce.org/Leadership-and-Management/Ethics/Code-of-Ethics/

14. Chapter 13: Engineering Design Section 13.1 – What is Engineering Design? • In order to create and build things, engineers must be involved in a design process • ABET definition of design: • “…the process of devising a system, component, or process to meet desired needs

15. Chapter 13: Engineering Design Section 13.2 – The Design Process 10 Stage Design Process: Identify the problem / product innovation Define the working criteria / goals Research and gather data Brainstorm / Generate creative ideas Analyze potential solutions Develop and test models Make the decision Communicate and specify Implement and commercialize Perform post-implementation review / assessment

16. Chapter 9: Visualization and Graphics Section 9.4 – First and Third Angle Projections 16 • The method for how to show and align the different 2D orthographic views leads to 2 main types of projections: • First Angle Projection (used in Europe) • Third Angle Projection (used in the U.S.) Third Angle Projection Third Angle Projection shown here is used predominantly in the U.S.

17. Chapter 9: Visualization and Graphics Section 9.10 – Pictorial Sketching 17 • Pictorial sketching: creating a view of the object in which all 3 dimensions are shown • 3 Types of Pictorial Sketches: • Axonometric (including isometric) • Oblique • Perspective

18. Codes of Ethics for Engineers Example: NSPE Code of Ethics, IEEE Code of Ethics, etc. http://www.nspe.org/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 of trustees. Avoid deceptive acts. Conduct themselves honorably, responsibly, ethically, and lawfully so as to enhance the honor, reputation, and usefulness of the profession.
