Engineers and Engineering Design 1
Seven Engineering Resources 1. People 2. Information 3. Time 4. Capital 5. Machines & Tools 6. Materials 7. Energy 2
Engineers Are problem solvers Have the following personal characteristics Creativity Resourcefulness Ability to visualize and think abstractly 3
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
Constraints on the engineering-design process Safety Reliability Economic considerations Quality control Environmental concerns Manufacturability Maintenance Human factors engineering (ergonomics) 5
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
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
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
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
