Incorrect ref to Darcy's law?[edit]

Article section 2.1 - Derivation of slope deflection equations When a simple beam of length and flexural rigidity is loaded at each end with counterclockwise moments and , member end rotations occur in the same direction. These rotation angles can be calculated using the unit dummy force method or Darcy's Law.

The link to the Darcy's Law page goes here: http://en.wikipedia.org/wiki/Darcy%27s_Law

This law is about fluid flow in a porous material - and I can't see the relevance. Is there another Darcy's law? I can't find it but the article should be corrected, either to the correct page, removed or explained. — Preceding unsigned comment added by 80.5.15.111 (talk) 16:36, 21 October 2012 (UTC)[reply]
