Engineering

An engineer has designed and built a prototype to improve the brake system of a car. Now that he has built a prototype, what is the next step that the engineer should take in the process?

• Test the prototype.

• Make sketches of the prototype.

• Identify constraints.

• Collect and analyze the test results.

What is the first step in the Design Process?

• Identify the Problem

• Construct a Prototype

• Develop Possible Solutions

• Optimize

A small group of people start sharing ideas. Some ideas may seem silly, but all suggestions are written down for further consideration. This activity is part of which step of the Design Process?

• Choose the Best Solution

• Brainstorm Design Solutions

• Research

• Communicate Results

During which step of the Design Process do you experiment with the prototype under controlled conditions and collect /record data?

• Test and Evaluate

• Construct Prototype

• Optimize

• Analyze Results

Which word best describes a constraint?

• option

• opportunity

• limitation

• goal

A team of engineers is asked to design a scooter that will be able to hold 150 pounds without breaking for less than $30. They decide that they will only use recycled materials. Which of the following is the team’s constraint?

• designed to appeal to kids

• made out of recycled materials

• must hold 150 pounds

• they do not have a scooter that does this

In order to develop ideas for a basketball shoe, a design team visits three different shoe stores. What part of the design process is this?

• Create a Prototype

• Research the Problem

• Select the Most Promising Solution

• Redesign

A design team built a prototype robot that is a vacuum cleaner. Their goal is for the robot to be able to vacuum people’s homes on its own with no human supervision. How will the team know if the robot prototype works after it is completed?

• Place it in someone’s home, and see if it can vacuum the carpets on its own.

• They should assume it works and starting making more prototypes.

• Place it in a grassy field, and observe to see if it can vacuum up dirt and sand.
