1) Which step in the engineering process determines whether the design needs to be changed? a) testing the solution b) researching the problem c) developing possible solutions d) communicating the solution 2) A restriction in the design process is considered to be a a) criteria b) constraint 3) Constraints in the design process a) limits the possiblilities of the design b) is a goal by which success will be evaluated 4) How do you know if the design is considered to be successful? a) the design met the criteria b) the design met all the constraints 5) Which best describes the purpose of a prototype? a) to test the design b) to research the problem c) to generate ideas for the design d) to help identify the problem being solved 6) Why do engineers build a prototype before manufacturing? a) prototypes test the concept and improve the design b) prototypes guarantee the product will NOT have any flaws 7) Criteria are.. a) things the design needs to do in order to be successful b) limitations on the design 8) Selecting a type of material because it's cheaper, even though it might not be as durable is an example o a) tradeoff b) criteria c) constraint 9) The process of giving up one quality or feature of a design to gain a different quality or feature a) criteria b) tradeoff c) constraint
