Doesn’t sorcery in reference 23 belong on another webpage? The listing of Zemic and Hottinger Baldwin Messtechnik look like advertisements. Comment by Ray Delcher — Preceding unsigned comment added by 216.24.45.40 ( talk) 21:37, 23 March 2023 (UTC)
anyone can give me more information about strain gauges? notify me at jib_zbz@yahoo.com
I understand that the error made by the engineers in the Murphy's Law story was that the strain gauges were wired up incorrectly in the Wheatstone bridge NOT that they were installed at 90 degrees. I quote the story at the linked page:

So I have altered this note slightly.-- Turtle ( talk) 21:59, 1 April 2008 (UTC)
In my opinion, this anecdote doesn't belong here anyway, but rather in the Wheatstone bridge article. It is an unnecessary distraction. 188.103.189.134 ( talk) 16:41, 24 April 2018 (UTC)
I'm not greatly fussed about "gage" and "gauge". But, if the article is "Strain gauge" and "Strain gage" redirects, then the spelling should be "gauge". If the article was "Strain gage" and "Strain gauge" redirected, then we should use "gage". Changed. Mr Stephen 22:20, 10 April 2006 (UTC)
Industry standard has been "gage". Omega and Micro-Measurements use gage throughout their sites. Most of the citations on this wiki page use gage. HBM seems mostly to have switched to gauge, despite the fact that their incredibly thorough book "An Introduction to Measurements using Strain Gages" uses gage. It is now available as a free .pdf from the HBM website under the title "An Introduction to Stress Analysis and Transducer Design using Strain Gauges", but the only change from gage to gauge is in the title. 12.230.47.87 ( talk) 23:01, 11 July 2017 (UTC)
The common metallic foil gauges do not use the piezoresistive effect, but rely on the geometric change, ie . Deleted. Mr Stephen 22:20, 10 April 2006 (UTC)
It is quite hard to create strain-free dummy gauges that are at the same temperature as the specimen. The usual technique is to use gauges made of Constantan or another alloy with a small thermal coefficient of resistance and a three-wire connection. Mr Stephen 22:20, 10 April 2006 (UTC)
Although Edward E Simmons developed a woven gauge, it was Arthur Claude Ruge at MIT who, at the same time in 1938, developed the first practical gauge where resistance wire was glued to a backing material.

I think the typical dimensions of a strain gauge should be clearly listed in order to improve this article.
It is not a good idea to have formulas in the introduction.-- Kölscher Pitter ( talk) 09:43, 10 January 2008 (UTC)
There are factual errors in the explanation.
The strain does not increase: strains are dimensionless and are usually expressed as a decimal fraction, a percentage or in parts-per notation. If the strain is 1%, every segment is stretched 1%, and the total sum of the segments also increases with 1%. Ssscienccce ( talk) 22:35, 13 September 2012 (UTC)
By concentrating on electronic strain gauges, the lede of the article suggests that strain guages were invented in the 1930s - in fact other types of (presumably mechanical) strain guages were in use earlier - Warrior to Dreadnought: Warship Development 1860–1905 by D K Brown (1997) refers to a series of strength trials carried out on the destroyer HMS Wolf in 1903 which involved the fitting of some 30 pairs of strain gauges (p. 184–185.). Nigel Ish ( talk) 22:11, 6 December 2013 (UTC)
While there are mechanical means of measuring strain, the example used in this section is not actually measuring strain. It is measuring displacement across a crack, not strain. I suggest removing this example. Meters ( talk) 16:05, 11 April 2016 (UTC)
This phrase is used a number of times in the article. It feels like a technical term in strain gaugery, so I think that it ought to be defined before it is used. I know little about the subject, so leave it to someone else. Macboff ( talk) 15:20, 28 March 2022 (UTC)
