Engineering Design Process Pretest

Which word best defines constraint?

• restriction or limit
• opportunity
• option
• success

When finding a solution to the design problem there is/are usually

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

Which answer (or answers) best describes criteria?

• how the model could fail

• the limits of the model

• what the model must look like

• what the model must do

What is the main goal of the design process?

• To write reports
• To make things
• To make charts and graphs
• To find solutions to problems

You begin to create a prototype of your design only to find that your solution isn't working at all. What should you do?

• Add more tape

• Go back to an earlier stage and choose another solution

• Blame your partner

• Keep going and hope it will be ok

A simple machine that allows you to test your design.

• solution

• design

• prototype

• failure point

The engineering process begins

• when you brainstorm new ideas 
• creating an advertisment
• identifying the need or solution to a problem

A prototype is a model that

• functions like the final solution would
• is made of the same materials as the final product
• is made after the final product is made

A manufacturer has developed a textured surface for plastic cups. The manufacturer has produced prototypes. Which of the following is the next step in the engineering design process?

• market the new textured cups

• redesign the textured surface

• test and evaluate the prototypes
