1.4 Practice Questions

The steps that engineers use to guide them to find a solution to a problem

• Scientific Method

• Engineering Design Process

• Iterative Cycle

• Decision Matrix

The standards that help engineers measure how well their design does its job.

• criteria

• constraints

• cost

• risk

The process of doing something again and again, usually to improve it.

• Brainstorming
• Probability
• Variable
• Iterations

What is the first step that should be completed in the engineering design process? Choose the correct answer.

.

• Design a prototype.

• Clearly define the problem.

• Refine and optimize the solution

• Develop several possible solutions.

What is the second step that should be completed in the engineering design process? Choose the correct answer.

.

• Design a prototype.

• Clearly define the problem.

• Refine and optimize the solution

• Develop several possible solutions.

What is the third step that should be completed in the engineering design process? Choose the correct answer.

.

• Design a prototype.

• Clearly define the problem.

• Refine and optimize the solution

• Develop several possible solutions.

Which is NOT an example of a tradeoff?

• use of plastic instead of steel in cars to reduce weight

• using cheaper equipment to record more of population

• use of paper grocery bag to carry groceries home

• use lower quality images for texts to send faster

Why is a decision matrix important for the engineering design process?

• assures all solutions are compared to criteria and constraints

• helps to identify the best solution

• removes emotion/opinion from any solution

• optimizes each solution

Engineers make prototypes

• with cheaper materials

• always to full scale

• to test and refine design

• only once; only one prototype needed
