Engineering Quiz Study Guide
prototype, model
Although the terms "model" and "prototype" are often used interchangeably, they are not the same thing.
define the problem
what is step 1 in the engineering design process?
identify the challenge
you need to recognize the heart of any problem before attempting to solve it. You must also know the constraints placed upon you. Are there any size, weight , and budget limitations?
quantity of ideas rather than quality
During a brainstorm session we want to focus more on
the shoes must cost less than $20 to manufacture
Engineers must understand the difference between requirements and constraints. Let's say a team of engineers is asked to design a pair of kids' tennis shoes for less than $20. They determine that the only way to manufacture shoes for this price is to use recycled materials. What is team's constraint?
research and brainstorm
Explore the site conditions, materials available, and public opinion. Has the challenge been met before? If so, how? If not, Why not ? Then, because the best solution to a problem is not always the first idea converted, exchange ideas in an open forum.
Identify the need
Identifying the "target population" or "target audience" occurs during which step of the engineering design loop?
go back to an earlier step of the Engineering Design Process and change the design to try to fix the product, then test the product again
If an engineer is testing a new product and notices that it does not always perform well, the engineer should
all of the above
If you wanted to build a new and improved type of sneaker, a good way to do background research and specify requirements for your new shoe would be to
a design engineer recognizes the need for a solution to a problem
In engineering, the design process begins with....
false
Lisa should take the first solution she comes up with and quickly build her prototype from that one solution
what materials do I need?
The Engineering Design Process starts by asking three questions about problems that you observe. Which of the questions below is NOT one of the three questions that help you define the problem for the problem for the first step of the Engineering Design Process
true
The engineering design process is a process used to solve a problem by creating new products, systems,or enviriments
evaluate it
The only way to know if your design will work in real-world conditions is to build a model, or prototypes, and then see if it works
a series of steps that engineers follow to come up with a solution to a problem
What is the Engineering Design Process?
all of these steps are part of the engineering design process.
Which of the following steps is not part of the engineering design process? Define the problem, Do background research,specify the design requirements, Brainstorm solutions, Choose the best solution, prototype the solution, test the prototype
what is a prototype
a working version of a created solution so that an engineer can test whether it is a good solution
true
as part of her background research, Lisa should talk to her grandfather to try to understand why he drops his fork.
true
before brain storming solutions, Lisa should do an internet search for silverware that marketed as easy for people who have shaky hands to use
test ideas
if your initial design doesn't fully solve the problem or meet the challenge (or can't do so for the money you have spend), go back and repeat the above steps. You'll know what doesn't work and be in a better position
have her grandfather test her new fork design
once Lisa has what she thinks is better fork, she should
design a solution
once you've settled on an idea to develop, prepare detailed drawings and engineering plans and solicit feedback. These designs may need to be modified depending on any feedback you receive
evaluate it
the only way to know if your design will work in real-world conditions is to build a model, or prototype, and then see if it works
build it
the only way to know if your design will work in real-world conditions is to build s model, or prototype, and then see if it works
true
the testing step of the Engineering Design Process usually involves several rounds of testing, finding new problems, and redesigning and testing again, before finding the final design
build it
this is the last step where you complete the project by creating the version that should work
develop possible solutions
what is step 3 in the engineering design process?
choose the best solution
what is step 4 in the engineering design process
create a prototype
what is step 5 in the engineering design process
test and evaluate
what is step 6 in the engineering design process
redesign
what is step 7 in the engineering design process
communicate
what is step 8 in the engineering design process
research the problem
what step 2 in the engineering design process?
many possible correct solutions
when finding the solution to an engineering design problem, there is/are usually...
both clockwise and counter-clockwise
when following the engineering design loop, the different stages can occur in which direction?
redesign
which step of the engineering design loop distinguishes an engineer from a technician?
