Poisson's Ratio of Rubber Apparatus Manufacturer,Supplier and Exporter in India

Product Code : ILS-EAST-10844

Indian Lab Suppliers supplies the Poisson's Ratio of Rubber Apparatus (Product ID: 10844) as part of its elasticity and surface tension range. It finds Poisson’s ratio for rubber from how a rubber tube thins as it is stretched.

Quick Answer

A cycle rubber tube about one metre long hangs from a heavy cast iron stand with a small pointer to mark its length. When it is loaded, the tube gets longer and narrower; comparing the fractional change in length with the change in the tube’s internal volume gives Poisson’s ratio, which for rubber is close to 0.5. Please confirm at quotation which accessories, such as weights and a volume-reading tube, are included.
