Engineering EOPA Review

Which describes the "test and evaluate " part of the Engineering Design Process?

• by thinking of possible solutions to the problem.

• considering the pros and cons of the possible solutions.​

• by trying them out to see how well they work.​

• thinking of ways the design could be better. ​

One day in November, Marisol opened her locker and had to quickly jump back to avoid the cascade of her belongings falling to the floor. “Oh no,” she yelled. “This isn’t cool!” Marisol quickly began to scoop her things back into her locker, but after putting everything away, she was late to her next class. Unfortunately, this wasn’t the first time the locker avalanche had happened. “I’ve got to find a way to organize my locker,” she said to herself. What stage of the Engineering Design Process is this?

• Identifying/Defining a Problem

• Developing Ideas

• Evaluating Ideas

• Criteria/Constraint

In order to generate possible ideas for her own locker, Marisol used her smartphone to take photographs of her friends’ lockers—or at least photographs of those that were organized. She would have to make an organizer herself. Since her parents only gave her a few dollars a week for allowance, she’d have to make an organizer for less than $3. This would describe what part of the engineering design process?

• The constraints

• The criteria

• Developing Ideas

• Evaluating Ideas

Marisol excitedly emptied her locker and carefully placed the makeshift shelf inside. “Success!” she thought to herself. It fit perfectly! She stacked her books on top of the sturdy shelf, and happily noted that it had no problem holding all of her books. One by one, she filled her hanging organizer with makeup, perfumes, extra pens and pencils, and—oh no! Before the pockets were even filled, the organizer fell to the ground. The paperclips weren’t strong enough to support the weight of all of her belongings. What part of the Engineering Design Process is this?

• Testing and Evaluating

• Optimizing Solutions

• Constraints and Criteria

• Using the prototype

The paperclips weren’t strong enough to support the weight of all of her belongings. So The next day, Marisol used hooks to hang her organizer and it held all of her personal items without falling. What part of the Engineering Design Process is this?

• Testing Solutions

• Improving Solutions

• Constraints and Criteria

• Evaluating Ideas

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

• Develop possible solutions(s) for the turbine and how it will fit the criteria needed

• Test the wind turbine on the mountains during the harsh winter months

• Redesign a new solution for this turbine

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

• Defining the specifications for the smart phone

• Finding the plasticity of a new alloy to be used for the smart phone case

• Trying the smart phone with a range of voltages to determine when it will fail
