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

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

“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

Chapter 13: Engineering DesignSection 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

Chapter 13: Engineering DesignSection 13.2 – The Design Process

10 Stage Design Process:1. Identify the problem / product innovation2. Define the working criteria / goals3. Research and gather data4. Brainstorm / Generate creative ideas5. Analyze potential solutions6. Develop and test models7. Make the decision8. Communicate and specify9. Implement and commercialize10. Perform post-implementation review /

assessment

Chapter 9: Visualization and GraphicsSection 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

Chapter 9: Visualization and GraphicsSection 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. Oblique3. Perspective

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:

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. Conduct themselves honorably, responsibly,

ethically, and lawfully so as to enhance the honor, reputation, and usefulness of the profession.
