Below are sample questions representative of the exercises included on this worksheet and related 8.126 Analyze Failure Points and Iterate skill assessments:

Problem 1Difficulty: Mastery

A team tested a portable phone stand. The wide base resisted tipping but folded too slowly. The hinge from a narrow-base model folded quickly but tipped easily. The rubber feet from a third model reduced sliding without changing fold time. Which final prototype plan best uses the test data?

ANarrow base only because it folded quickly

BWide base with the faster hinge and rubber feet, followed by tipping, sliding, and fold-time tests

CWide base only because it resisted tipping

DRubber feet only because sliding was reduced

Solution & Explanation:The plan combines the best characteristics from different prototypes and retests all relevant criteria.

Problem 2Difficulty: Mastery

A model water wheel produced more electricity after the blade width was doubled, but water splashed out of the channel and the total collected water downstream dropped by half. Which conclusion is not justified by the data?

AThe wider blade design is automatically best because electricity increased.

BThe wider blades improved one output but created a water-control failure.

CThe next design should test a blade width between the original and doubled width.

DSplashing should be measured in the next test.

Solution & Explanation:Electricity improved, but the water-control failure means the wider blades are not automatically the best overall design.

Problem 3Difficulty: Mastery

Which summary best communicates the outcome of a design iteration?

AThe new bridge is better, but no measurements are needed.

BThe bridge looks stronger, so testing can stop.

CThe team changed materials and does not need to record the reason.

DAfter adding gussets, load capacity increased from 9 kg to 13 kg, but the bridge still missed the 15 kg goal because the deck split; next revision will reinforce the deck.

Solution & Explanation:A strong summary reports evidence, whether the criterion was met, the remaining failure mode, and the next revision.
