The reference to the NASA document: Barrett, Richard T. (1 March 1990). "(NASA-RP-1228) Fastener Design Manual" This is used as a source for the static and dynamic friction of wood and other materials. This document has absolutely nothing to do with friction and includes no such reference data. 149.167.140.87 (talk) 03:31, 20 February 2021 (UTC)
- Not done: Have a look at Table IV on page 20. It seems the data the document is used as a source for is present. Volteer1 (talk) 03:48, 20 February 2021 (UTC)

The description of normal reaction N is completely wrong. N is NOT the the force that compresses the two surfaces together. N is a pair of electrostatic repulsion when the surfaces are brought in contact. The statement that N=mg is also partially incorrect since it is only true on a horizontal flat surface. On an incline plane N=mg cos(theta) where theta is the angle of incline. One should also explain that the statement N=mg does NOT mean that these the normal reaction is the same as gravity. The ambiguity must be explained; the magnitude of normal reaction is equal to the magnitude of gravity (on flat horizontal plane) but N and mg are two forces acting on two different points of action (mg acts at center of mass and N acts at a point of surface of contact), the direction of gravity is opposite of direction of N AND the nature of gravity and N are different (gravity & electrostatic force). These big mistakes must be corrected. They mis-inform physics students Pari-sterzinger (talk) 02:13, 17 June 2021 (UTC)
- Not done: It's not clear what exactly you want to be changed (please state it in the suggested "x to y" format), and what would actually be helpful would be finding some sources to cite for this information (which you have provided exactly zero examples of) RandomCanadian (talk / contribs) 03:36, 17 June 2021 (UTC)
Proposed merge of Friction Acoustics into Friction
[edit]I don't see any particular reason for "Friction Acoustics" to be an independent article at this time. I recommend merging into the section under "Energy of friction" Polyamorph (talk) 13:17, 3 February 2022 (UTC)
- Weak oppose: while I agree that the current article is weak, the topic has sufficient scope to be developed. Hence, I think that ímprove rather than merge, would be the better action. Klbrain (talk) 19:59, 23 August 2022 (UTC)
- Closing, given the uncontested objection and no support. Klbrain (talk) 10:08, 27 December 2022 (UTC)

Plinius the elder and Vitruvius are Romans not Greeks and not even remotely contemporary. 151.35.217.119 (talk) 14:29, 6 July 2023 (UTC)
- Done by removing the "Greek" as is was superfluous. Ldm1954 (talk) 20:20, 31 August 2023 (UTC)
