Below are sample questions representative of the exercises included on this worksheet and related 11.46 Designed Materials and Molecular Structure skill assessments:

Problem 1Difficulty: Mastery

A designer wants a heat-resistant polymer part that can still be repaired or reprocessed under special factory conditions. Which modification best fits the goal?

ARemove all interactions so the part flows at room temperature.

BUse a fully permanent network that decomposes before any rearrangement.

CUse a low-Tg waxy polymer with no reinforcing interactions.

DIntroduce reversible or exchangeable crosslinks instead of only permanent crosslinks.

Solution & Explanation:Reversible or exchangeable crosslinks can improve heat resistance during use while allowing controlled network rearrangement for repair or reprocessing. This directly links molecular architecture to design tradeoffs.

Problem 2Difficulty: Mastery

The image shows a weighted decision matrix for a lightweight protective panel. Scores are 1 to 5, and higher is better. Criteria weights are strength 0.40, density 0.25, cost 0.20, and recyclability 0.15. Which candidate has the highest weighted score?

ACandidate A.

BCandidate C.

CCandidate B.

DCandidate D.

Solution & Explanation:Candidate B scores 5(0.40) + 4(0.25) + 3(0.20) + 3(0.15) = 4.05, which is higher than the other candidates. Materials selection often balances properties rather than maximizing only one.

Problem 3Difficulty: Mastery

A student claims, 'The strongest material is always the one with the strongest individual bonds.' Which response best reflects materials chemistry?

ABond strength never matters for any designed material.

BBond strength matters, but defects, microstructure, chain alignment, and interfaces also control performance.

COnly density matters, so molecular structure can be ignored.

DInterfaces matter only in pure elements with no phases.

Solution & Explanation:Macroscopic strength is not determined by one bond in isolation. Cracks, grain boundaries, chain orientation, crystallinity, and composite interfaces can dominate failure behavior.
