Analysis of Tensile Strength of Block Gauges

When block gauges wrung together are pulled from each other in the direction perpendicular to the wringing surface, the maximum force required to separate them is termed tensile strength. Although there are reports on qualitative study of this strength, these seems to be none that deals with its theoretical analysis.This report gives analysis of tensile strength and presents the causes of this strength. The findings are summarized as follows:1. Tensile strength is considered attributable to viscosity and surface tension of oil trapped between the wringing surfaces.2. Tensile strength is not suitable as a force for evaluating wringing force as it is greatly influenced by oil distribution between the wringing surfaces.
