....I opened a book (on Statics) and found a scrap of paper where I had scribbled out the equation
E/2G=1+V
and then re-arranged to solve for E or V.
E=2G(1+V)
V=(E-2G)/2G
...the problem is I can't remember what the formula was for (remember a Statics book) and I went forwards and backwards through the book and can't find the reference.
Anyone have an idea?
H.W. Morrow, Statics and Strength of Materials, 7th Ed.
Solved! Go to Solution.

Whats a book?
The first thing that came to mind was Stress/Strain relationships
E - Modulus of Elasticity
G - Shear Modulus of Elasticity / Modulus of Rigidity
V - Poisson's Ratio

An artifact found in a dusty old building referred to as "The Library". Most of my students have never been in this building.

Thanks, I found it with your tip
Hook's Law for Shear.
G=E/(2(1+v))
The relationship between elastic constants.
You're all going to be banned with language like that! 😉

oooohhh. So its like real world "cloud" storage.. I get it now.. . gee why would you ever need one of those places. Have old people never heard of google before? 😉
Google or Wiki...because EVERYTHING on the internet is true or factual!
Ahhh, verbal history. Forced the young-uns to pay attention. Mind you, the mallets from the stoneworking tools came in handy when they didn't.
