Engineers and Scientists

• Scientists seek technical answers to understand
  natural phenomenon
• Engineers study technical problems with a
  practical application always in mind
• For example
• Scientists study atomic structure to understand
  the nature of matter engineers study atomic
  structure to make smaller and faster microchips

3
The Engineer and the Engineering Technologist

• Main difference between the two is
• Engineers design and manufacture machines and
  systems, while engineering technologists have the
  technical know-how to use and install the
  machines properly
• An example
• The technologist identifies the equipment
  necessary to assemble a new CD player the
  engineer designs said CD player

4
What do Engineers do?

• Three variables
• Discipline/Major
• Position/Function
• Industry

5
Engineering Functions

• Design, Development, Research, Test, Analysis,
  Production, Sales, Technical Support
• Get into eight groups
• Develop 2 bullet points describing the
  engineering function you have been assigned

6
Design Engineer

• Largest number of engineers employed
• Responsible for shape and specifications of
  components
• Safety, reliability and integrity of the
  components
• Requires coordination with all other engineers

7
Development Engineer

• Take the knowledge from researchers and apply it
  to a specific application
• Incorporate findings into prototypes to test
  feasibility for use in the next generation of
  products.

8
Research Engineer

• Perform investigations with experiments and
  computers.
• Work in a university or National Lab environment.
• Typically requires a PhD.

9
Test Engineer

• Verify the integrity and reliability of products
  before introduction to the public
• Simulate conditions that a product will be
  subjected to in typical use throughout its life

10
Analysis Engineer

• Uses mathematical models and computational tools
  to provide information to design, development,
  and research engineers
• Typically specialists in a technology area
  important to production such as heat transfer,
  fluid flow, vibrations, etc

11
Production Engineer

• Turn designs into large scale production as
  efficiently as possible
• Responsible for maintenance of machines and the
  inventory and supplies

12
Sales Engineer

• Trained to identify which products are right for
  the customer
• Technical background to understand the customers
  needs and to answer questions and concerns

13
Technical Support Engineer

• Specify installations and set-ups of products
• Trained to troubleshoot and fix technical problems

14
Engineering Majors

• Biomedical, Electrical, Computer, Chemical,
  Civil Environmental, Materials, Aerospace,
  Mechanical
• Rearrange into eight different groups
• Develop 2 bullet points describing the
  engineering major you have been assigned

15
Biomedical

• Application of engineering principles to
  biological systems to meet the needs of the
  medical community
• Work with genetics to produce bioengineered
  products

16
Electrical

• Design and develop electronic circuits
• Work in biomedical field developing non-intrusive
  diagnostic techniques
• Work with transmission and distribution of power

17
Computer

• Focused on design of computer hardware and
  software as well as personal and commercial
  security
• Develop and design electronics to interface with
  computers
• Similar to computer scientists but focus more on
  the hardware

18
Chemical

• Take what chemists do in the lab and apply the
  fundamental engineering, physics, and chemical
  principles to it

19
Civil Environmental

• Concerned with form and function, appearance and
  integrity of buildings and other structures
• Environmental engineers focus on waste management
  and cleaning of contaminated sites and to reduce
  or eliminate harmful waste

20
Materials

• Develop new materials to meet the needs of
  society as well as the processes that create them
• Work to ensure that a material meets the
  performance needs of its intended application by
  designing testing procedures to ensure
  requirements are met

21
Aerospace

• Involved in flights within and also outside of
  the Earths atmosphere
• Separated into categories of
• Aerodynamics
• Propulsion
• Structures
• Controls
• Orbital Mechanics
• Life Sciences

22
Mechanical

• Concerned with machines and mechanical devices
• Involved in design and development, production,
  control, operation of these devices
• Areas include design and controls and thermal
  sciences
• Develop computational tools to aid the design
  process

23
Homework (due in one week)

• Pick three blocks in the cube (Figure 2-1) and
  write a job description for that engineer.
• None of your blocks can haveany similar
  variables.

24
Profiles in Engineering

• Combine groups into four groups
• Each group take one of the specified profiled
  engineers
• Study the bio in the text
• Present this person to the group
• What do they do?
• Where do they fit into the cube?
• Do they seem to enjoy engineering?
• Does their life seem to be in balance?
