EGR 122 Midterm (Ch 1-8) Exam Questions With
Complete Answers
the 3 design roles - ANSWER client, user, designer
1st task for a designer - ANSWER begin with questions about client's wishes to translate them
into meaningful objectives, constraints, and functions
who must the designer satisfy - ANSWER everybody (user and client)
conceptual design - ANSWER stage where basic questions of form and content for a design
are established (including the nature of the goals of the designed item)
detailed design - ANSWER occurs after conceptual design (and after preliminary or
embodiment design), when specific details particular to the design are resolved and therefore,
general design issues have been identified
engineering design - ANSWER thoughtful process for generating plans or schemes for
devices, systems, or processes that attain given objectives while adhering to specified
constraints
objective - ANSWER feature or behavior that we wish the design to have or exhibit
,constraint - ANSWER limit or restriction on the features or behaviors of the design
artifacts - ANSWER artificial, man-made objects... the "things" or devices that are being
designed
function - ANSWER thing a designed device or system's supposed to do
means - ANSWER a way or a method to make a function happen
form - ANSWER shape and structure of the artifact as distinguished from its material
specification - ANSWER a scale on which the achievement of a design's functions can be
measured. Specifications are engineering statements of the extent to which functions are
performed by a design. Specifications may specify values for certain functions or design
features, procedures for calculating functions or behaviors of the design, or performance
levels that must be attained by the design
metric - ANSWER standard of measurement;
measure how well we achieve a design's objectives → allows us to evaluate design alternatives
what is the ultimate product of most contemporary design - ANSWER fabric specifications
, fabric specifications - ANSWER provide a detailed description of the designed device so that it
can be assembled/manufactured, thus separating "designing" from the "making"
what do engineers usually produce pysically - ANSWER prototypes and proofs of design... not
typically artifacts
what happened in the 1981 hyatt regency catastrophy - ANSWER walkways at the second and
fourth floors were hung from the same set of threaded rods that would carry their weights
and loads to a roof truss. This is b/c the fabricator wasn't able to procure threaded walkways
long enough to suspend the 2nd floor walkway from the roof truss. The supports of 4th floor
weren't designed to carry 2nd floor in addition to its own, so a collapse occurred... this is why
communication between the designer and manufacturer is key.
why are engineering design problems challenging? - ANSWER b/c they're usually ill structured
and open ended. ill structured b/c you can't simply use a formula to find the answer. open
ended b/c there can be several acceptable solutions.
studio aspect - ANSWER learning by doing
project management - ANSWER tracking of the scope, schedule, and spending to accomplish
the goals and objectives of a project
project management: scope - ANSWER deciding what a project must accomplish to be
