What is the first step in the engineering process?

• Testing the prototype

• Defining the problem

• Building the solution

• Evaluating the solution

Why is it important to define the problem clearly in the engineering process?

• To save time and resources

• To ensure the solution is effective

• To avoid unnecessary testing

• All of the above

After defining the problem, what is the next step in the engineering process?

• Building a prototype

• Testing the solution

• Brainstorming possible solutions

• Research

What is a prototype in the context of engineering?

• A final product ready for use

• A detailed plan or blueprint; a model or a computer simulation.

• A formula

• A theoretical idea without physical form

Why is testing a prototype an essential part of the engineering process?

• To ensure it works as intended

• To identify any flaws or areas for improvement

• To gather data for further development

• All of the above

What does the evaluation step involve in the engineering process?

• Building the final product

• Reviewing test results and making improvements

• Marketing the product to consumers

• Documenting the design process

According to the video, how many times might engineers test and refine their prototypes?

What lesson can be learned from Willis Carrier's experience with inventing modern air conditioning?

• A) Success often comes without failure

• B) Persistence and learning from failures lead to better solutions

• C) Testing is unnecessary if the initial idea is strong

• D) Engineering processes are only for large projects

Why is failure considered a valuable part of the engineering process?

• It indicates a lack of skill

• It HIGHLIGHTS our mistakes and provides opportunities to learn and improve.

• It should be avoided at all costs

• It is irrelevant to the final outcome

What is the main purpose of the engineering process as described in the video?

• To follow a strict set of rules

• To create perfect solutions on the first try

• To systematically solve problems through testing and refinement

• To limit creativity and innovation
