Imagine you are an engineer, and you are trying to design an air filter that will successfully reduce the amount of air pollution being released into the air by a factory. You need to consider constraints that will limit your design as well as the criteria that will be used to judge the successfulness of your design.

Question

Identify each factor from the list below as either a constraint or a criterion.

This question is worth a total of 2 points. To earn 1 point, you must get two or three responses correct. To earn both points, you must get all four responses correct.

(2 points)
constraint criterion
filter must keep working reliably for at least 6 months before needing replacement

filter has to fit in the space that can be accessed for cleaning and replacement

filter cannot exceed budget allowance for cost

filter must reliable remove at least 95% of pollutants

Answer 1

constraints:
- filter must keep working reliably for at least 6 months before needing replacement
- filter has to fit in the space that can be accessed for cleaning and replacement
- filter cannot exceed budget allowance for cost

criterion:
- filter must reliably remove at least 95% of pollutants
