A system is ________________________.
a set of separate parts that work together for a purpose
a set of interacting parts that work together
a product that can move across boundaries
What are the two types of systems?
natural and engineered
input and output
components and boundaries
engineered and grouped
All systems are made up of parts. These parts are called:
(a)
Matter, energy, or information that enters a system is called an (a) .
A product of a system is called an (a) .
The digestive system is an example of a _______________.
natural system
engineered system
A video game is an example of an _________________.
natural system
engineered system
A (a) defines the edges or limits of a system.
Why is creating system models important?
What is STEP 1 of the Engineering Design Process?
define the problem
identify criteria and constraints
brainstorm multiple solutions
What is STEP 2 of the Engineering Design Process?
iterative testing
brainstorm multiple solutions
identify criteria and constraints
What is STEP 3 of the Engineering Design Process?
select the most promising solution
brainstorm multiple solutions
iterative testing
STEP 4: After brainstorming multiple solutions, we (a) the most promising solution.
STEP 5: Create a (a) of the selected solution.
STEP 6: After creating the prototype, what do we do with it?
test it
fix it
make it better
STEP 7: After testing the prototype and gathering feedback, we do __________ ____________.
(a)
STEP 8: Last but not least, after we do the iterative testing and we make improve our model, we ______________ the solution.
design
fix
share or communicate
The (a) of a design problem are features or qualities the solution should have.
The limitations the engineers face during the design process are called (a) .
Who needs the solution, what the solution should do, and how the solution will address the
problem or need are examples of _______________.
criteria
constraints
Cost, time, resource availability, laws and scientific understanding are examples of _________________.
criteria
constraints
Design testing that is repeated many times is called ____________ _____________.
(a)
The iterative design process involves:
testing and analyzing
refining a product, system, or process
all of the above
none of the above
The purpose of the iterative testing process is to:
giving up one design advantage in order to keep another
improve the quality and usefulness of a design
design a solution for a determined problem
A ______________ is the act of giving up one design advantage in order to keep another.
criteria
tradeoff
optimize solutions
