See drop-down box for suggested article edit guidelines:

Be bold - if you know something about Cornwall then put it in! We value your contributions and don't be afraid if your spelling isn't great as there are plenty of spelling and grammar experts on clean-up duty!
Articles on settlements in Cornwall should be written using the standard set of headings approved by the UK geography WikiProject's guideline How to write about settlements.
At WikiProject Cornwall we subscribe to the policies laid down by Wikipedia - particularly civility and consensus building. We are aware that the wording on Cornish entries can sometimes be a contentious topic, especially those concerning geography. You don't have to agree with everything but there is no excuse for rudeness and these things are best solved through consensus building and compromise. For more information see WP:CornwallGuideline.
These pages are not platforms for political discussion. Issues relating to Cornish politics should be restricted to those pages that directly deal with these issues (such as Constitutional status of Cornwall, Cornish nationalism, etc) and should not overflow into other articles.
Most of all have fun editing - that's the reason we all do this, right?!

Irrelevant information should be removed

The paragraph "As a truss type" about the University of Phoenix Stadium, wrongly mentioned as "the Arizona Cardinals's new (multiple–use) stadium" is out of place here. Trusses with parts that are under tension or compression are a common engineering feature and this example is not clear in support of, nor does it resemble the Royal Albert Bridge design. Further does the information about "a grass field that rolls on rails" strike me as not being relevant. I think it should be removed. VanBurenen 10:48, 15 August 2007 (UTC)[reply]

The whole point of the lenticular truss is missed

I quote "The two spans are lenticular trusses with the top chord of each truss comprising a heavy tubular arch in compression, while the bottom chord comprises a pair of chains. [Each of the trusses is simply supported and therefore no horizontal thrust is exerted on the piers], which is crucial in view of the curved track on either side. Between these two chords are supporting cross-bracing members and suspension standards which hang beneath the bottom chord to carry the railway deck which is a continuous plate beam."

Subquote "[Each of the trusses is simply supported and therefore no horizontal thrust is exerted on the piers]" This is absolute nonsense.

The simple beauty of the lenticular design is commonly missed. The fact is that when the arch component of the lenticular truss is loaded it tends to expand along its length and, conversely, when the chain component is loaded it tends to contract along its length. These two opposing components may be designed to balance so that overall no change of length occurs. Because, by design, there is no change of length it follows there is no horizontal thrust exerted on the piers.Puffingbilly (talk) 13:05, 29 March 2021 (UTC)[reply]

Construction location

The section on construction talks about the "Devon shore", "Devon span", "Devon approach spans" and "Devon truss", but the bridge was built wholly within Cornwall. The whole span at the time of construction was in Cornwall, from the west bank of the Tamar to the east bank. I will remove these anachronisms unless there is any sensible reason to keep them. Bodrugan (talk) 01:36, 11 July 2022 (UTC)[reply]

Most modern readers wouldn't understand that the county boundary has moved and Wikipedia generally refers to current political boundaries. St Budeaux makes no mention of having been in Cornwall, and even Cornwall doesn't appear to mention where the boundary was or when it was changed. Before removing "these anachronisms" from this article, I suggest that the Cornwall article, at least, is corrected.

Whatever is decided, we need to keep a distinction between the two banks and the two trusses. 12:29, 11 July 2022 (UTC)
