1. Engineers and Engineering Design 1

2. Seven Engineering Resources 1. People 2. Information 3. Time 4. Capital 5. Machines & Tools 6. Materials 7. Energy 2

3. Engineers  Are problem solvers  Have the following personal characteristics  Creativity  Resourcefulness  Ability to visualize and think abstractly 3

4. Engineering  The systematic application of mathematical, scientific, and technical principles, to yield tangible end products that meet our needs and desires  Has evolved as civilization has progressed, with each generation building on the accomplishments of its predecessors 4

5. Constraints on the engineering-design process  Safety  Reliability  Economic considerations  Quality control  Environmental concerns  Manufacturability  Maintenance  Human factors engineering (ergonomics) 5

6. Design Principles  Design in the result of a formal, sequential process.  Design problems seldom arise in a clearly defined form  Design is driven by profit motive and market  Design is the result of goal-oriented research  Design must be continually checked, refined, and improved. 6

7. When designing a device or process  Thought should be given to how it will be  Manufactured  Operated  Maintained  Replaced  Disposed of  And who will  Sell  Operate  Take care of it 7

8. Mathematical Modeling  To find a mathematical relationship that behaves in the same ways as the objects or processes under investigation.  Computers have greatly improved the power and use of mathematical models by performing computations that are very long, very complicated, or repetitive. 8

9. Engineers  Use the language of mathematics to express mathematical ideas precisely  Analyze and evaluate the mathematical thinking and strategies of others  Create and use representations to organize, record, and communicate mathematical ideas  Select, apply, and translate among mathematical representations to solve problems  Use representations to model and interpret physical, social, and mathematical phenomena 9
