When solving problems, the series of steps that engineers follow is called _______.
the engineering method
the engineering design process
the engineering problem
the scientific method
In engineering, the design process begins when…
information about an existing product is gathered by an engineer
an engineering design team comes up with ideas for a new product
a design engineer recognizes the need for a solution to a problem
Identifying the “target population” or “target audience” occurs during which step of the engineering design loop?
Identify the Need
Research the Problem
Develop Possible Solutions
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 the team’s constraint?
The shoes must be designed for kids
The shoes must be made out of recycled materials
The shoes must cost less than $20 to manufacture
During a brainstorming session we want to focus more on:
quantity of ideas rather than quality
quality
quality of ideas rather than quantity
Which step of the engineering design loop distinguishes an engineer from a technician?
Construct a Prototype
Test and Evaluate a Prototype
Redesign
Although the terms “model” and “prototype” are often used interchangeably, they are not the same thing. A _______ is used to test different aspects of a product before the design is finalized. A ______ is used to demonstrate or explain how a product will look or function.
model, prototype
prototype, model
When following the engineering design loop, the different stages can occur in which direction?
clockwise
counter-clockwise
both clockwise and counter-clockwise
in any direction, including shortcuts
The engineering design process is iterative. This allows engineers to…
become proficient at different engineering software applications
find the most optimal solution to a design problem
Incorporate both math and science concepts into a design problem
When finding the solution to an engineering design problem, there is/are usually…
only one possible correct solution
a very limited number of possible correct solutions
many possible correct solutions
What is considered the criteria when looking at a project?
the requirements the solution must meet
the limitations and restrictions on a solution
the solution
The constraints of the project are
the limitations and restrictions on a solution
the requirements the solution must meet
the final design
When selecting a promising solution you should do the following
Consider the pros and cons of all the solutions and then create them all to see which one works best
Consider the pros and cons of all possible solutions but choose one solution to move forward with
Consider the pros and cons of the all solutions and make sure that you understand the problem
Which of the following is most likely part of the testing and evaluation stage of designing a smart phone?
Writing an advertisement for the smart phone
Trying the smart phone with a range of voltages to determine when it will fail
Finding the plasticity of a new alloy to be used for the smart phone case
Defining the specifications for the smart phone
In which step do you consider the question "is the problem worth solving"
Present a Solution
Identify a Problem
Design Brief
Generate a Solution
In which step of the Design Process do you document the project in a Project Portfolio?
Present Solution
Construct and Test Prototype
Evaluate Solution
Develop a Solution
A tire company is creating a new tire for a motorcycle to drive off-road in sandy and rocky conditions as well as on roads. Engineers developed three different tread patterns. Based on the engineering design process, the next step the company should take is to:
Send out a questionnaire about tires to the public
Research the properties of rubber
Select which tread design will be best
See which tire is the most expensive
Rob and his team have been chosen to build a wind turbine at a local ski resort that needs to generate electrical energy and withstand the harsh environment of the mountains. Rob and his team have done their research on the problem. What would be the next step for the team?
Create a prototype of the wind turbine
Test the wind turbine on the mountains during the harsh winter months
Develop possible solutions(s) for the turbine and how it will fit the criteria needed
Redesign a new solution for this turbine
Students have a box of ice pops to take to their soccer game to sell on a hot day. The students know they need a device to keep the ice pops from melting for 3 hours. They have a $15 budget. Which step of the engineering design process does this demonstrate
Identify the problem
Redesign
Test and evaluate
Develop possible solutions
Brian is trying to create a motorized scooter for his engineering design project. Which of the following should he do during his research step?
Look up current scooter designs online
Read the instruction manuals for other scooters
Ask professionals who work at the local scooter shop
All of the above
