loads to add here - on my to-do list...examples, pictures, expanded definition, causes, types etc I'm planning to fully redo this article so if you have any suggestions I'm happy to incorporate them into the page once i get to it Sam Lacey 00:15, 18 May 2007 (UTC)

## Axial direction

What does it mean to be axially directed? Squideshi 23:37, 28 September 2007 (UTC)

## Table of examples

Does any article have a list of compressive strengths for different common materials? Cesiumfrog (talk) 00:46, 31 May 2011 (UTC)

Something like this would be nice: Ultimate tensile strength#Typical_tensile_strengths. Even better would be to have compressive and tensile strengths side by side. Tensile strengths seem to be MUCH higher than compressive strengths. That's why going to the bottom of the ocean is often a lot harder and more expensive than going to space.

Indeed it is quite frustrating to find so little information about compressive strength of usual materials or of material specifically formulated to present a high compressive strength — Preceding unsigned comment added by Guioseppe.rojma (talkcontribs) 01:56, 17 March 2012 (UTC)

## Orders of Magnitude are important

So a small plastic container may have a compressive strength of only 5 times that of concrete? — Preceding unsigned comment added by 60.241.181.62 (talk) 00:29, 26 March 2013 (UTC)

The text was "Concrete can be made to have high compressive strength, e.g. many concrete structures have compressive strengths in excess of 50 MPa, whereas a material such as soft sandstone may have a compressive strength as low as 5 or 10 MPa. By contrast, a small plastic container might have a compressive strength of less than 250 N." An editor had deleted this without an explanation. These examples are valid and were in the article to show readers some ranges of values of compressive strength. Note that the units for the small plastic container wer in N and not MPa. This should be restored to the article. Pkgx (talk) 21:27, 23 April 2013 (UTC)
