Can shoe soles scratch a vinyl record?
Budget: €12 – €18 EUR
I need a clear, science-based explanation of whether—and under what conditions—a modern rubber or polyurethane shoe sole can leave permanent scratches on a vinyl record. The study should zero-in on two factors:
• Surface friction between typical outsole compounds and the record’s PVC groove wall
• The effect of applied pressure (static load and possible dynamic impacts)
Please ground the discussion in tribology and materials-science principles rather than anecdotal evidence. Wherever possible, reference published coefficients of friction, hardness (Shore A/D), and any existing wear data for both materials. If additional laboratory data are required, outline a concise test plan (contact geometry, load range, measurement tools such as stylus profilometry or optical microscopy) and estimate the threshold force at which groove damage becomes likely.
Deliver a brief, well-structured report (PDF or DOCX) that includes:
1. Methodology and assumptions
2. Calculations or empirical data used
3. Reasoned conclusion on scratch risk under typical and worst-case scenarios
4. Any visual aids—graphs, micrographs, or comparative tables—that clarify the findings
Concise, evidence-backed writing is preferred over lengthy theoretical digressions.
