What major functions do engineers perform?
1. Research- making new discoveries and finding uses
2. Development- production of a function able device/ process
3. Design- optimizing/ making easier to produce/ improving performance
4. Production/Testing- mass production + quantity control
5. Construction- Production on a site
6. Operations- managing facilities and networks
7. Sales- consumer creator link, creating a market
8. Management- using background for managing
9. Consulting- solving problems
What type of eduction is required to be an engineer?
1. Bachelors degree at a credited school (ABET or CAEB)
2. Exams- Fundamentals of Engineering test- Engineering in Training (EIT)
3. Practice for 4 years- principles and practice exam- licensed engineer
What important ethics are related to engineering situations?
Engineers use knowledge and skill for the advancement of human welfare. They need
to be honest and impartial, increasing reputation of the engineering profession.

What are the important principles of the problem solving process?
identification of a need, problem definition, researching, constraint, criteria, alternative
solutions, analysis
What are the steps in the design process?
Identify the need, research and gathering info, develop solution (alternative solutions),
choose a solution (analysis), construct a prototype, test and evaluate
How to analyze solution/ identifying strengths and weaknesses?
, Efficiency
Cost
Safety
Functionality
Availability of materials
Durability
How to develop details of a solution?
Scale model
Inventor (dynamic simulation)
Orthographic Isometric drawing
Techno CNC + 3D printing
How to develop, test, and redesign prototypes?
Test for safety and durability
Test for efficiency
How to explain components of set up, machining, casting, molding, welding, and
finishing?
Turning- lathe
Milling- makes square objects
Casting- turns liquid into mold
Welding- arc, spot, gas (oxyacetylene)
Undercutting- welding reduce cross sectional strength
Finishing- painting
How to identify and use common hand tools
Straight edge- ruler
VIC (vernier caliper)- measures inside/outside distanxes
How to identify and properly use fasteners?
