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?
