Below are sample questions representative of the exercises included on this worksheet and related 9.60 Designing Energy Conversion Devices skill assessments:

Problem 1Difficulty: Mastery

Which written recommendation best completes an engineering argument for an energy conversion device?

AChoose Prototype 2 because the team likes it and trade-offs should not be discussed.

BChoose any prototype because all energy conversion devices meet the same criteria.

CChoose Prototype 2 because repeated tests show it meets the required output within the cost and safety limits, though it has a mass trade-off.

DChoose Prototype 1 because it had one impressive trial even though it violates the safety limit.

Solution & Explanation:A strong recommendation connects evidence to criteria and constraints and acknowledges trade-offs. This is the kind of reasoning expected when evaluating competing solutions.

Problem 2Difficulty: Mastery

A water-wheel generator for a stream is shown with solid panels that block most water flow. The design produces electricity but could disrupt the stream. Which redesign best balances energy conversion and environmental constraint?

AIgnore water flow because environmental constraints are unrelated to engineering.

BRemove the generator from testing and measure only water depth.

CBuild a full dam immediately because maximum blockage should maximize the score.

DUse spaced paddles or a bypass channel, then test output and water flow before finalizing the design.

Solution & Explanation:A better design should maintain useful energy conversion while reducing disruption. Testing both electrical output and water flow addresses the trade-off.

Problem 3Difficulty: Mastery

A graph shows two solar charger prototypes with overlapping error bars for stored energy after 1 hour. Prototype A has a slightly higher mean but costs more. What conclusion is best?

AError bars mean the experiment failed and no evidence can be used.

BPrototype B is definitely better because lower cost always overrides data uncertainty.

CThe data do not clearly prove A stores more energy, so cost and additional trials should inform the decision.

DPrototype A is definitely better because any higher mean proves a real difference.

Solution & Explanation:Overlapping error bars suggest the difference in stored energy may not be clear. The team should consider uncertainty, cost, and possibly collect more evidence.
