Final Exam Material Flashcards
Saliency Model and who is involved
Urgency, legitimacy, and Power; Primary, Secondary, Tertiary Stakeholders
For the three types of stakeholders, how many attributes do they have?
Primary: all attributes; Secondary; two of the attributes; Tertiary: only one
what is urgency?
wants a say
what is legitimacy
has a right to say
what is utilitarianism?
greatest benefit/ least consequence for the greatest amount of people.
what is power?
ability to influence
duty- based ethics
universal principles that everyone should follow, like being honest, fair, respect human lives, etc.
rights-based ethics
respect other people’s rights such as rights of life, liberty, and dignity.
scoring
analyzing the most promising ideas typically when we use WDM
ranking
uses evaluation criteria based on “better” or “worse” performance
screening
uses the requirements and disregards any concepts that don’t meet requirements
Under Prototyping, what is Solid works Model considered as
part focused/ part comprehensive virtual
what is a rights holder?
anyone whose legal or human rights could be impacted by the project
what is scale?
collection of multiple parts and helps engineers consider everyone and all the impacts
what are the different types of scales
spatial, temporal, governmental, organizational
temporal scale
Temporal scale is a measure of change over time
spatial scale
spatial scale is a measure of change across space
governmental scale
provincial, regional, federal, global
threshold needs
unsaid, important needs; if it wasn’t there people would riot
expressed needs
vocalized needs
latent needs
something a stakeholder may not know they need
actual cost vs cost committed
costs, effort, money and resources currently spent; impact on the costs that may be needed later in the process (material costs, manufacturers, bad design, etc.)
target design specifications
basically the requirements and evaluation criteria
sensitivity analysis
switching around the weights for the EC to see the robustness of the concept
validation
ensuring target design specs meet the stakeholders needs
simple system
closed and predictable; deterministic
complicated system
made up of a lot of simple systems; like a car; many elements and deterministic
complex system
hard to predict and control; not deterministic
verification
makes sure the final product meets target design specs
audience
who are we presenting for, what do they know/ don’t know, tone and vocab
purpose
goals and wants for presentation; whether informing or persuading; the outcome of communication
context
why, where, what do we have available to us, how much time do we have to prep; what led us to do this
what is sustainability?
evolves the environment, society, and the economy
bearable
overlap of society and environment; things like shoreline cleanup, urban green spaces
environment
how can we better our earth; lowering carbon emissions, biodiversity, etc.
viable
overlap of economy and environment; renewable energy, source efficiency, etc.
economy
how does this help with employment, prosperity, trade, businesses, innovation, etc.
equitable
job creation, skill enhancement, tax reductions
society
health, safety, human rights, education, opportunity
cable will permanently deform if…
stress> yield strength (o > o_y)
part begins to break if…
stress > ultimate tensile stress (o > o_ut)
to avoid permanent deformity
stress must be equal or less than yield strength
what are the 7 C’s
clear, concise, complete, concrete, courteous, considerate, correct
water jet pros and cons
best for flat 2D materials; wastes material, can’t control depth of cut, can only cut certain materials (cardboard, stuff that can’t get wet)
laser cutting
good for etching or engraving
SLS printing
