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?
