Engineering Design Process Pre-Test

A technology company has identified the need for a smaller laptop computer that weighs less, but they do not have enough knowledge about how to build it.

What would be the next logical step engineers would take to design and produce this laptop computer?

• Build a new type of laptop battery

• Research current laptop technology

• Build a prototype computer

• Define the problem

An emergency-equipment company makes warning-signal flares. The company wants to redesign a flare so that it produces light for a longer period of time.

After the company thinks of ideas and picks one, what is the next step in the design process?

• Prototype their solution

• Define the problem

• Iterate to improve the prototype

• Test and evaluate their old flares

A group of engineers designed and constructed a flying car prototype. Their goal is for the car to enable people to safely fly to and from work instead of getting stuck in traffic jams.

How will the engineers determine that this prototype meets their design requirements?

• Have a test pilot attempt to fly it from one location to another.

• See if the car can hover one meter above the ground for 20 minutes.

• Drive in the car at highway speeds on an interstate roadway at nighttime.

• Drive the car at night

Engineers plan on developing a new drill for use on oil rigs. What should the engineers do first in order to develop the new drill?

• Conduct research on features for a new drill

• Determine the materials needed to build the new drill

• Build a prototype of the new drill

• Define the problem

Some scientists want to design a system of instruments that will evaluate ocean currents, temperatures, and winds in order to predict weather patterns.

What should they do before they produce the first complete working version of the system?

• Improve the design of the system

• Evaluate the results of the system

• Build a prototype of the system

• Communicate the results of their research

What is the purpose of building a prototype?

• To test the product and make sure that it is the best solution to the problem

• To make sure that the product is in compliance with government regulations

• To determine the design constraints for the product

• To estimate the cost of the final product

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.

• If other teams copy the design of their robot

Your group plans to build a model plant. When should you decide upon the criteria you will use to test your technological design?

• After the model is built

• After the model is tested

• Before the model is built

• After your team runs out of money

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

• Not enough research was conducted

A factory is producing a new machine designed to reduce the amount of air pollution in houses. The machine was produced and sold to the public. After several months, reports show the machine is not working correctly.Which of these most likely caused this outcome?

• The proper cost analysis was not performed.

• The manufacturing of the machine was done over several months

• The prototype was not tested before use by the public

• Not enough research was conducted
