1. Introduction to Engineering 2014-15

2. The great strength of Engineering is its
DIVERSITY
 It is not unusual to technicians & technologists working in research labs or engineers selling & maintaining technical products.
 Technical specialties have become so sophisticated that it is not unusual to find individuals who are very focused and do not have the title of either engineer or technologist.
 Consider the design and manufacturing of aircraft:
Scientists - research new materials, such as composites.
Research engineers - study the scientists’ input and develop
feasible aircraft designs.
Developmental and design engineers - work on implementing
“flyable designs”.
Manufacturing engineers & Technologists - preparing to
manufacture the selected design.
Technicians & craftspersons - involved in fabrication & testing
all components, as well as assembling the aircraft.

3. Origins Came into use in Middle Ages
Origin of word is from “engine” and “ingeneous” which in latin means to create.

4. The Engineering Profession
Engineering is the profession in which a knowledge of mathematical and natural sciences, gained by study, experience, and practice, is applied with judgement to develop ways to utilize, economically, the materials and forces of nature for the benefit of mankind.
What is engineering?
Difficult question!
Engineers do so many different things.
Engineers perform so many different functions.
Here’s the standard definition:

5. What is the difference between an Engineer and a Scientists
Scientist conduct research by forming a hypothesis and then testing their hypothesis with experiments.
Engineers are asked to solve problems by using different designs.

6. The Engineering Design Process
Need
or Opportunity
Problem Definition/
Specifications
Data & Information
Collection
Development of
Alternative Designs
At the heart of engineering is the Engineering Design Process.
This is a step-by-step method with the objective of producing a device,
structure, or system that satisfies a need.
Evaluation of Designs/
Selection of Optimal Design 1.
Need established by customer
missile for launching satellite
Implementation of
Optimal Design
Opportunity identified by company
little pieces of paper which could stick onto almost anything
but could be removed easily without leaving any trace
2/28/2019 2.
Need generally described by a set of specifications (specs)
performance specifications (e.g. Weight, size, speed,
safety, reliability)
economic specifications (e.g. Cost, profit)
scheduling specifications (e.g. Production & delivery
dates

7. The Engineering/Technology Profession
Engineering/Technology focuses primarily on the applied aspects of science and engineering, aimed at preparing graduates for practice in that portion of the technological spectrum closest to product improvement, industrial practices, and engineering operational functions.
Engineering Technology
draws upon the same body of knowledge as engineering
centers more heavily upon the applications related to
manufacturing
testing
construction
maintenance
field service
marketing
This could be for you if you enjoy building and making
things and making things work
Contains elements of
science  engineering
mathematics  mechanical skills
abstract thinking  laboratory skills

8. ENGINEERS TECHNOLOGISTS
Scientists would most likely be found performing functions toward the left-hand side of the spectrum, while technicians and craftspersons would most likely be found doing the functions toward the right.
Engineers & Technologists would see a great deal of overlap in their functional interests. They would most likely perform functions in the middle part of the spectrum.
Scientists
the basic nature of things
trying to understand the “why” of things
Engineers & Technologists
trying to understand the the “how” of things
how to take the findings of the scientists and use them
to develop useful products for humankind
2/28/2019
Engineers - conceptual development of new products
Technologists - improving existing technologies
building & refining products

14. Project Based course
Team members learn a required skill for construction of the project.
Team is provided kit with most of the parts.
At least one part must be machined in the CNC.
Project will include presentations, reports, and deliverables throughout the semester

16. Why should you want to be an Engineer?
Use math and science skills
Get to play with some really cool “toys”
Work outdoors, indoors, city or rural setting
Make a good living
Highest paying Bachelor’s degree
Work with talented people
Solve problems
Make people’s lives better
Do something useful for the world
Respect
Engineers are professionals
People take their opinions seriously
Job Satisfaction - Hopefully you are happy with the life work you choose. If not, find one that satisfies you!
Challenging Work - intellectually stimulating; solving “real- world” problems.
Intellectual Development - “exercises” your brain, developing your ability to think logically and to solve problems.
Financial Security - Important, but not essential! Do something you enjoy!
Variety - an enormous variety of jobs!
Benefit Society - just about everything you do in this field is of benefit to the world we live in.
How things work - engineering gives you an idea on how the things around you work.
Prestige - highly respected! We play a role in competitive- ness, standard of living, security, and public safety.
Environment - The latest and greatest tools and environment.
Creativity - Playing with imagination and possibilities which can lead to new and meaningful connections/outcomes while interacting with ideas, people, and environment.

17. Employment Opportunities
As you can see, nearly two-thirds of the engineering/technology jobs occur in industry. But, as the world around us continually changes, there is always the opportunity for entrepreneurs and small business. You have probably heard that people may not end their careers in the same company they started with. You may change your job five or more times before hanging it up.
The opportunity exists!
