Below are sample questions representative of the exercises included on this worksheet and related 9.10 Engineering Criteria, Constraints, and Tradeoffs skill assessments:

Problem 1Difficulty: Mastery

A final design review shows that a prototype meets cost, efficiency, and environmental criteria, but several stakeholders cannot use it safely without assistance. What is the best revision goal?

AIgnore the stakeholder issue because the other scores are strong

BImprove accessibility while preserving as much cost, efficiency, and environmental performance as possible

CApprove the design because accessibility is never part of engineering

DRemove environmental criteria to make the review shorter

Solution & Explanation:Stakeholder safety and usability are central to engineering design. The goal is to optimize the design without discarding other important criteria.

Problem 2Difficulty: Mastery

A team must choose a water-saving irrigation system for a school garden. Drip tubing saves the most water but clogs without regular maintenance. A soaker hose saves slightly less water and is easier for students to maintain. A sprinkler is easiest but wastes the most water. If students will maintain the system, which choice is best justified?

ANo system, because criteria conflict

BSprinkler, because easy maintenance is the only criterion

CSoaker hose, because it balances water savings with realistic maintenance by the users

DDrip tubing, because the highest water savings always wins

Solution & Explanation:The users' ability to maintain the system is part of the design context. The soaker hose offers a practical balance of water savings and maintainability.

Problem 3Difficulty: Mastery

A remote seismic station must run for one year without service. Battery A is cheap but lasts 5 months. Battery B costs more and lasts 14 months. Battery C lasts 12 months but fails in cold tests. Which choice best satisfies the real constraints?

ABattery C

BBattery A because it has the lowest upfront cost

CBattery B

DBattery A

Solution & Explanation:The station needs one year of unattended, reliable operation. Battery B meets the duration and avoids the cold-test failure.
