Homework Help Overview

The discussion revolves around the shear modulus, specifically seeking historical context and definitions related to its formulation. Participants express a need for background information on the origins of the shear modulus and its relationship to other material properties.

Discussion Character

  • Exploratory, Conceptual clarification

Approaches and Questions Raised

  • The original poster attempts to find historical context regarding the definition of the shear modulus and its significance. Some participants provide definitions and relationships to other moduli, while others express uncertainty about the historical aspect.

Discussion Status

The discussion is ongoing, with participants exploring different angles of the inquiry. While some definitions and relationships are provided, there is no consensus on the historical figure or context behind the shear modulus.

Contextual Notes

The original poster has a specific requirement to write a report, indicating a need for detailed background information that is currently lacking in the discussion.

I was wondering if anyone could please point me in the direction of some background info on who (and why) someone defined the equations definition of the shear modulus, I've searched in google and wiki and havnt found anything useful. Just a link or something would be great
 
Physics news on Phys.org
It is similarly defined as the modulus of elasticity

Modulus of Rigidity = Shear force/ Shear strain

It is also related to the modulus of elasticity E by

[tex]G=\frac{E}{2(1+\nu)}[/tex] where v is the Poisson's ratio.
 
thanks :) but I was more wanting the person that defined it, I've to write a report on it, and need some background info... Which I can't seem to find
 
In that case, I do not know as well. Sorry.
 
All good :) thanks
