A focus group usually consists of groups of 5-7 people that are surveyed. The data collected from a focus
group should be considered:
Opinion

Design Problems
The class races their electric cars that they built. A tape measure is glued to the floor between the lanes. Ali
videotapes the races. Whitney looked at the videos and recorded the position, by the tape, of each car in each
frame, so she could plot their speed on a graph. What program should she use to record the data?
Excel
An engineer designing a laptop is told the device should be convenient to carry. This is likely to affect the
design process, creating constraints on:

the judges to explain the process used to create it. Which design process step will the club complete?
Communicate the Results
The purpose of a case study when conducting problem-solving research is to:
assess the current understanding of a problem.

the school's Engineering Design program. Which question is most likely to be asked in the problem analysis
phase of the engineering design process?
What does the community need to know about the program?
The advancement of scientific knowledge is promoted by using:
the tools of technology and engineering.

exactly. The size specification is considered a:
Criteria
The criteria and constraints of a product or system and the determination of how they affect the final design
and development are called:
Requirements
When looking at the front view of a visual object in an orthographic drawing, the missing dimension from
the view would be the:
Depth
A wise designer should realize:
it is inappropriate to address some design problems
Which type of design project would testing a design using computer-based simulation be required?
Truss Bridge
Identifying both desired elements and limitations of a product or system is called:
Requirements
The requirements for a product to function efficiently is called:
The Criteria
A new office building has been planned and will be built in sunny, Phoenix, AZ. The roof will have a three
foot overhang and the exterior walls will be constructed using twelve inch adobe brick. The design features
of this building have been established based on:
environmental conditions
Three-dimensional models are typically used for:
simulating and testing design ideas
If a product does not meet the established criteria during production, issues related to its:
quality control must be investigated
. A newly constructed bridge was inspected to evaluate the load capacity of the bridge. During the inspection,
fatigue cracks and stress fractures were discovered on the deck and supports. After reviewing the original
plans, it was discovered the bridge was not built to original specifications (requirements). What did the
engineers most likely ignore when designing the bridge?
Criteria and Constraints
A linear (straight forward) approach to develop a product will predict which of the following outcomes?
Each phase is addressed independently, one step at a time.
The productivity of a design may be established by testing a:
Prototype
When solving design problems it is important to clearly understand the problem. To accomplish this it is
important to:
Define the Problem
Before a design solution can be refined, it should first be:
Tested
Shirley and Bob are testing three mathematical models to see which one is best for modeling the power
consumption of their school. They should determine which model is best by choosing the one that:
most closely matches the current power consumption.
Dr. Sandy, an engineer at Handy and Associates, is working on a project. To communicate procedures, flow
charts, drawings, graphics, symbols, spreadsheets, graphs, time charts, and webpages will be included in her:
Engineering Design Journal
A group of students are developing ideas for a new video game console system. At which point in the design
process should they discuss regarding each design before making a prototype?
Selecting the Best Solution
The general requirements and limitations that are incorporated into the design of a structure are known as:
Criteria and Constraints
A problem-solving process that is used to generate ideas, model, test, and communicate new products and
processes is called a:
Engineering Design Process
When refining a design, which method would yield information to improve the efficiency of the design?
Computer Simulations
Which design constraints are likely to compete with each other when designing a fuel cell for a rocket?
Weight and power output
The process used to make a design or system as effective or efficient as possible.
Optimization
There are many scientific concepts that are used by engineers and designers. Which of the
following would NOT be one of these concepts?
Colors that Match Green
When testing electric motors, students discovered that when the input power increased, the speed of
the motor shafts (rpm) increased. Which graphical representations would best enable the students to
systematically examine this relationship?
Line Graph
Which step of the engineering design process would use a graph to communicate the results?
Evaluating the Design
When designing a roof for a greenhouse a variety of angles must be measured and cut accurately. What tool
should be used to measure the angles?
Protractor
Which activity occurs first in the design process?
Researching similar products
A working model used to test a design during development is called a:
Prototype
Many airplanes are constructed largely out of aluminum even though steel is a stronger material. This is an
example of:
optimizing design trade-offs.
A design challenge is given that says, "create a bird house, but do not let it cost more than $20.00 in
