Formulas[edit]

fB = F·L3 / (3·E·I) φB = F·L2 / (2·E·I)

It would be helpful to identify "f" and "B" in this equation.

Image misleading[edit]

Image under topic "End Load Cantilever Beams" shows a beam in mode 6 vibration, which is quite different from the deflection of an "end-loaded" beam. 209.254.20.114 (talk) 22:46, 21 September 2010 (UTC)[reply]

Fixed. Hermanoere (talk) 23:31, 22 June 2015 (UTC)[reply]

Too shallow[edit]

This article is too shallow to be useful.

What's especially missing are proofs and also indications on whether the results are exact or approximate.

Also missing is which of the listed methods should be used under which circumstances. — Preceding unsigned comment added by 84.243.199.239 (talk) 09:55, 30 January 2015 (UTC)[reply]

Added statements about assumptions under which the formulas were developed.Hermanoere (talk) 23:05, 19 June 2015 (UTC)[reply]

Units[edit]

Could someone add the units to the formula ? I tried my best but can not found the SI unit for Elasticity modulus ?_? 2A01:E35:8B31:3450:B982:FF4E:558A:854F (talk) 20:19, 27 March 2015 (UTC)[reply]

Added quick discussion of units.Hermanoere (talk) 23:05, 19 June 2015 (UTC)[reply]

Suggest merging this with Beam_(structure)[edit]

An article on beams already exists. But that article only talks about types of beams and stresses, not deflection. Since this article (Deflection_(engineering)) talks about deflection only of beams, it should really be a subsection in the other article. Hermanoere (talk) 14:14, 26 June 2015 (UTC)[reply]

The subject of the article applies not only to beams. Shafts are subject to the same issues. --Turbojet (talk) 11:56, 31 August 2021 (UTC)[reply]

Linear relationship Load - Deflection[edit]

It would be helpful to highlight there is a linear relationship between the load and deflection. --188.167.156.157 (talk) 09:26, 9 December 2016 (UTC)Martin Medved[reply]
