Reliant Lab Poisson’s Ratio of Rubber Apparatus for Verification of Incompressibility

• Stand Material : Cast Iron
• Tube Material : Rubber

Features

• Volumetric Measurement System: Utilizes a water filled rubber tube connected to a graduated capillary to measure microscopic lateral contractions through volume changes.
• Uniform Rubber Specimen: Equipped with a high grade, elastic rubber tube of consistent thickness to ensure uniform deformation throughout the experiment.
• Precision Graduated Capillary: The attached glass capillary tube allows for high-sensitivity readings of water level shifts, representing the change in internal volume.
• Heavy-Duty Support Frame: Constructed with a stable vertical pillar and a robust base to maintain perfect alignment of the tube and scale during weight application.

Applications

• Study of Material Elasticity: Helps students understand the behavior of polymers and elastomers under tensile stress.
• Verification of Incompressibility: Used to demonstrate that for materials like rubber, the volume remains nearly constant during deformation .
• Advanced Mechanics Instruction: Serves as a core experiment in undergraduate physics and engineering to bridge the gap between simple tension and volumetric strain.
• Laboratory Skills Training: Develops proficiency in reading capillary levels and performing multi variable calculations in material science.
