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.

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 Chapter 1: The History of Engineering Section Introduction 2

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 Chapter 1: The History of Engineering Section Introduction 3

What do Engineers do?  Three variables  Discipline/Major  Position/Function  Industry

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

Engineering Quotes  “Scientists investigate that which already is; Engineers create that which never has been.” Theodore von Karman Theodore von Karman  “Engineering is the application of science to the common purpose of life” Count Rumford 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 Arthur M. Wellington

Steps to become an engineer I. BSEE - Complete Bachelor’s of Science degree in electrical engineering; more than 200 accredited programs II. FE Exam - Pass Fundamentals of Engineering Examination; 8 hr. exam typically taken during senior year. III. 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. IV. PE Exam - Pass Professional Engineer’s Examination; 8 hr. exam covering design, engineering analysis and ethics. V. PDH’s - Maintain engineering competency through yearly professional development and life long learning activities

Professional 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 c. striving to increase the competence and prestige of the engineering profession; and d. supporting the professional and technical societies of their disciplines. Code of Ethics Fundamental Principles: Engineers uphold and advance the integrity, honor and dignity of the engineering profession by:

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 14

Chapter 13: Engineering Design Section 13.2 – The Design Process 10 Stage Design Process: 1. Identify the problem / product innovation 2. Define the working criteria / goals 3. Research and gather data 4. Brainstorm / Generate creative ideas 5. Analyze potential solutions 6. Develop and test models 7. Make the decision 8. Communicate and specify 9. Implement and commercialize 10. Perform post-implementation review / assessment 15

16 Chapter 9: Visualization and Graphics Section 9.4 – First and Third Angle Projections  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 shown here is used predominantly in the U.S. Third Angle Projection

17 Chapter 9: Visualization and Graphics Section 9.10 – Pictorial Sketching  Pictorial sketching: creating a view of the object in which all 3 dimensions are shown  3 Types of Pictorial Sketches: 1. Axonometric (including isometric) 2. Oblique 3. Perspective

Codes of Ethics for Engineers  Example: NSPE Code of Ethics, IEEE Code of Ethics, etc. Fundamental canons:  Engineers, in the fulfillment of their professional duties, shall: 1. Hold paramount the safety, health, and welfare of the public. 2. Perform services only in areas of their competence. 3. Issue public statements only in an objective and truthful manner. 4. Act for each employer or client as faithful agents of trustees. 5. Avoid deceptive acts. 6.
