Below are sample questions representative of the exercises included on this worksheet and related 6.107 Prototype with Low Cost Materials skill assessments:

Problem 1Difficulty: Mastery

A rover wheel hub must connect to an axle and be easy to assemble in the field. The team is debating tight tolerances versus a self-aligning funnel shape. Which statement best captures a mastery-level reason to use low-cost prototypes here?

ALow-cost prototypes are only for appearance and cannot inform assembly design.

BBecause assembly reliability depends on human handling and alignment, cheap full-scale prototypes let the team observe misalignment failures and refine guiding geometry before specifying tight tolerances.

CField assembly can be predicted perfectly from CAD, so physical models add no value.

DTight tolerances are always best, so prototyping is unnecessary.

Solution & Explanation:Field assembly is affected by real hand motions and alignment errors. Low-cost full-scale prototypes can reveal where parts catch or misalign, enabling geometry changes (like funnels) before committing to strict tolerances.

Problem 2Difficulty: Mastery

A student team is designing a wearable band clasp with one-handed operation. They have two latch ideas: a hook-and-slot and a press-to-release tab. Early users struggle, but the team is unsure whether the problem is geometry or hand position. Which low-cost prototyping adjustment best diagnoses the problem?

AImprove the clasp by making it shinier so users feel confident.

BCreate adjustable prototypes where hook depth or tab travel can be changed in small steps, and video-record one-handed closing to see where fingers slip or misalign.

CPick the press-to-release tab because it sounds simpler and stop testing.

DReplace the design with a completely different band size so it fits better.

Solution & Explanation:Adjustable low-cost prototypes let the team vary geometry systematically. Video observation reveals hand positioning and failure moments, separating geometry issues from user technique and guiding targeted redesign.

Problem 3Difficulty: Mastery

A folding stool hinge is failing after repeated use. The designer thinks the hinge fails because the load path creates bending on a thin section, and wants to test a gusset idea. Which low-cost prototyping method best evaluates the gusset idea before metalwork?

AMake full-scale hinge mock-ups from plywood with and without a gusset, apply repeated loading with weights, and inspect where cracks or loosening starts.

BMake a small model hinge and assume failure modes scale perfectly.

CAdd a gusset to the metal hinge immediately without testing because gussets always help.

DSwitch to a stronger bolt and ignore the hinge geometry.

Solution & Explanation:The question is whether the gusset changes the load path and delays failure. Full-scale low-cost mock-ups can reveal loosening/crack initiation trends under repeated loads before investing in metal fabrication.
