In this article we will provide you a thesis report on Whittmore-Petrenko Proving ring or simply proving ring. In this project on proving ring we will provide you background history on proving ring, types of rings, materials required, design, construction and working of Proving ring. The project covers Strength of materi
als among various other subjects of mechanical engineering.
Proving ring is a force transducer concept designed, analyzed and developed to be used in laboratory experiments to measure forces. The elastic behavior of the proving ring was analyzed using Castigliano’s second theorem and the results were found to be about 1% accurate.
The proving ring is a metal ring equipped with means of measuring deflection when under load. The concept of proving ring was created originally by Whittmore and Petrenko at the US National Bureau of standards.
Force transducers are commonly used in engineering applications like weighing scales, verification of material testing machine, thrust measurement etc. Ring shaped transducers provide an ease in manufacturing and are widely used for the measurement of force.
The proving ring is a elastic metal ring with a means of measuring deflection when it is under load. It is used to measure force. The ring is currently used in laboratory exercises and in research projects in fluid mechanics.
