Discussion Overview
The discussion centers around the selection of an appropriate adhesive for bonding a strain gage to steel, specifically in the context of expected strains around 10%. Participants explore options that are readily available and express concerns regarding the performance of these adhesives under high strain conditions.
Discussion Character
- Technical explanation
- Debate/contested
Main Points Raised
- One participant inquires about suitable adhesives available at hardware stores for attaching a strain gage to steel, with a focus on the expected strain of approximately 10%.
- Another participant suggests thin cyanocrylate as a potential adhesive but expresses concern about its reliability at high strains, emphasizing the importance of proper surface preparation.
- A different participant mentions using super glue in the past for low strain applications, noting that it may only be advisable for inexpensive strain gauges and recommends checking manufacturer guidelines for more expensive gauges.
- One participant questions the feasibility of achieving 10% strain in steel, indicating skepticism about the initial premise.
Areas of Agreement / Disagreement
Participants do not reach a consensus on the best adhesive, and there are differing opinions regarding the appropriateness of super glue and cyanocrylate for high strain applications. Additionally, there is uncertainty about the possibility of achieving 10% strain in steel.
Contextual Notes
Participants highlight the importance of adhesive selection based on strain levels and gauge cost, but do not resolve the implications of using specific adhesives under high strain conditions.
