## Stroud Notation

## Stroud Notation

(OP)

I have a handbook entitles Engineering Formulas 7th Edition by Kurt and Reiner Gieck. In it, they describe something called "Stroud notation", in which equations are written with units included for each term. I was taught to do this in college, but there was no mention of a notation named after somebody. Google and MillionShort are not finding anything.

Has anyone out there heard of this?

Perhaps.

Cubature Error Bounds for Analytic Functions-- https://www.ams.org/journals/mcom/1973-27-123/S002...(This one doesn't apply. I found several papers on-line about cubature that refer to "Stroud's notation.")

A Handbook of Torsional Vibration-- https://books.google.com/books?id=LmEBdI7KJfcC&...'s%20notation%22&f=false(This one says the following: "To distinguish between units of mass and force, Stroud's notation is used in this book. In this notation, Lb., Ton and Kg. are units of force, being the accepted weights of lb., ton and kg. masses." This is closer to what Gluck had in mind [I have the 3rd edition], but it's not the same.)

That's interesting. I Googled "Stroud notation". You did "Stroud's"?

1) state the equation, say I = (bd^3)/12

2) list each variable, depending on the level of pedantic-ness ...

b = Xin

d = Yin

show a picture or a 1000 words describing these

3) then substitute ... I = (X*Y^3)/12 = Zin4

rather than I = ((Xin)*(Yin)^3)/12

I find the unit balances to be idiot resistant. If my length works out to s

^{-2}, I know I have goofed up somewhere.--

When the expression gets too busy I separate the quantities and the units into two clusters for clarity.
