Academic Honesty

Students are expected to conform to the highest standards of

honesty and integrity. Students are encouraged to discuss

course material to foster the motivations of ideas and produce

high quality works. They may work together in the

preliminary stages of individual homework assignments but

the final work must reflect their originality and individual

efforts. Plagiarism is considered a disciplinary offence which

can result in reduced grades, failed subjects and suspension

from the university.

ABET’s Definition of Engineering

ABET (The Accreditation Board for Engineering and Technology )

Recognized in the United States as the sole agency responsible for

accreditation of educational programs leading to degrees in

engineering

Engineering is the profession in which a knowledge of the

mathematical and natural sciences, gained by study,

experience, and practice, is applied with judgment to develop

ways to utilize, economically, the materials and forces of

nature for the benefit of [hu]mankind.

Engineering: Definition

20

Profession

Math and natural sciences

Knowledge acquired by study, experience, and professional

practice

Knowledge applied with judgment

Attention must be paid to constraints (economic, materials,

forces of nature)

Benefit of mankind

Not based solely on trial, error, intuition

According to definition:

Engineering is a profession like medicine, law, etc. that aspires to high standards of conduct and

recognizes its responsibility to the general public.

Engineering uses scientific, technological, and

mathematical knowledge to solve practical problems.

22

Engineering v.s. Science

23

Science:

– Investigation, understanding, and discovery of nature, its

composition, and its behavior (i.e., “laws of nature”)

– Why

– Build (experiments, tools, devices, etc.) to learn

Engineering:

– Manipulating the forces of nature to advance humanity

– How

– Learn to build (products and services useful for humans)

24

Scientists Understand why our world behaves the way it does (“laws of nature”)

Study the world as it is

Thinkers

Engineers

Apply established scientific theories and principles to develop cost-

effective solutions to practical problems

Cost effective Consideration of design trade-offs (esp. resource usage)

Minimize negative impacts (e.g. environmental and social cost)

Practical problems: Problems that matter to people

Change the world

Doers

The scientist seeks to understand what is. The Engineer

seeks to CREATE what never was.

--- Theodore von Karman

What Do Engineers Do?

Engineers Can Do Anything

31

Invent – Develop a new product, system, or process that

has never existed before

Innovate – Improve an existing technological product,

system, or method

Design

Development

Improvement Manufacturing

Invention Analysis

Management

The focus of an engineer’s work typically falls into one or

more of the following areas:

Research : Advanced field

- explore, discover and apply new principles

Development : Lab to market

- transform ideas or concepts into production processes

e.g., develop and implement ways to extract, process and use raw

materials such as petroleum and natural gas.

32

Design : Develop specs for manufacturing, construction, etc.

- link the generation of ideas and the production

33

- Successful engineering design improves quality of life

while working within technical, economic, business,

societal, and ethical constraints.

Example: Design under Constraint

1) Design products. 2) Design machinery to build and test these products. 3) Design the systems that ensure the quality and efficiency of the manufacturing process. 4) Design, plan and supervise the construction of buildings, highways, transit systems.

Production and testing : Verify integrity, reliability,

quality

- manufacture and assemble components or products

Analysis: Use math models to aid in R&D

Operations - maintain equipment and facilities

Construction : Build

- prior to construction organizes bids, during

construction supervises certain components of process

35

Management - optimize the use of resources (equipment,

labor, finances)

Education - teach engineering principles in university and

industrial settings

Consulting - provide specialized engineering services the

clients. May work alone or in partnership other engineers.

36

Whether the end result is a product, a process or

service, engineers need to consider safety, reliability,

and cost-effectiveness.

Engineering is a career based on logical, systematic problem solving, generally in high-tech, industrial, or scientific fields.

37

An electrical engineer may design a GPS for your vehicle.

A pharmaceutical/chemical engineer may find a cure for disease.

A computer engineer may build a computer the size of your watch.

A mechanical engineer may create a robot to discover water on a planet.

An agricultural engineer may evaluate the effects of global warming on food production.

Engineers Work to Solve Many Kinds of Problems

38

So why not make it a major part of your life's

plans?

Today, men and women are successfully practicing

engineering in a variety of companies around the world.

Others are preparing themselves for careers in

engineering.

39

Discussion Questions

What product or system would make your

life better?

Is this an invention or an innovation?

What type(s) of engineer(s) might work on

this project?
