Basic Engineering Concepts

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

• Research the Problem
• Develop Possible Solutions
• Communicate the Design
• Identify the Need

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

• Test and Evaluate
• Select the Most Promising Solution
• Construct a Prototype
• Share Results

When finding the solution to an engineering problem, there is/are usually 

• only one possible correct solution
• a very limited number of possible correct solutions
• many possible correct solutions

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

In the design world, limitations are known as:

• Constraints
• Criteria
• Iterations
• Data

It is important when brainstorming to:

• Limit your ideas to what is "real"
• Come up with as many ideas as possible
• Gravitate to a few ideas
• Keep it brief in time

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 go ahead and build a prototype of this design.
• Place it in a grassy field, and observe to see if it can vacuum up dirt and sand.

A factory produced a new type of refrigerator designed to use less electricity. The machine was manufactured and sold to the public at Target, Wal-Mart, and K-Mart. After several months, reports showed that this refrigerator was not working correctly. 
Which choice below is the most likely cause?

• The proper cost analysis was not performed.
• The designers did not test other types of machines.
• They did not rigorously test and modify the prototype

If your initial design doesn't fully solve the problem or meet the challenge, you must go back and revise your design. This is part of which step in the Design Process?

• Construct a Prototype
• Redesign
• Identify the Need
• Develop Possible Solutions

An engineer has designed and built a prototype to improve the brake system of a car. 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.
