What is engineering? - answer The profession in
which knowledge of mathematical and natural
sciences, gained by study, experience, and
practice, is applied with judgment to develop ways
to use, economically, the materials and forces of
nature for the benefit of mankind.
Scientists versus engineers - answer Scientists ask
"why?"
- Attempt to understand how the natural world
functions
- Results of their work is the expansion of
knowledge
- Final product is often publication of research
work
Engineers also ask "why?" and:
- Apply concepts learned from scientists
- Solve problems relevant to society
Result: The development and improvement of a
product or process
Problem (engineering) - answer A difficult or
demanding question.
,Engineering design process - answer A continuous,
iterative procedure in which a feedback loop forces
convergence to an acceptable solution for a
specified problem.
Engineering design process - answer 1. Define
2. Imagine
3. Evaluate
4. Create
5. Test
Overall: improve
Step 1: define - answer Identify the problem or
product innovation. It must be clear, concise, and
unambiguous.. Define the working criteria and
goals the design must address. Research and
gather data. Construct a formal statement of the
problem.
Step 2: imagine - answer Creatively develop as
many potential solutions to the problem as
possible (nothing is too wild/illogical; everything is
recorded). Host at least one brainstorming session
(the more mentally diverse team members the
better). Consider ways to change an existing
solution to create ideas for a new solution.
, Step 3: Evaluate - answer Potential solutions are
subjected to technical and financial analysis.
Evaluate using a decision table (give weight to
each working criteria established in step 1,
totaling 100 points. Score each potential solution
based on this criteria)
Step 4: Create - answer Create model that enables
visualization and exploration of the operational
aspects of the design.
common model types in create step - answer -Full
scale model or prototype
-Scale model
-Diagram or graph
-Computer model
-Mathematical mode
Step 5: Test - answer Perform a variety of tests on
each model to compare and evaluate against
working criteria (overall goals). These results
inform decisions made about the future of the
project. Final improvements are made after
testing. Performing a final review and assessment
of performance, efficiency, quality and costs. Detail
