Not sure I understand why the disambiguation comment about stiffness = joint stiffness should be deleted --Mylesclough 05:05, 12 October 2005 (UTC)

Thanks for restoring that. I did create a Joint stiffness entry for the purpose --Mylesclough 06:37, 20 October 2005 (UTC)

[edit] compliance in liquids

I was looking to find out about compliance as in fluid dynamics.

Hello, With so many people not having corrected this I am a bit reluctant to do so... but: Why do you write P and say that stiffness 'k' is usually measured in Newtons per metre? If it IS measured in Newton per metre I think it should say F(orce) per metre. As I understand it: P is the pulse and is mass x velocity so the unit is: Kg m/s . F is the Force and is mass x acceleration so the unit is: kg m /s^2 . (1N = 1 kg m /s^2 it is NOT 1 Kg m/s). greetings, Mattijs Lingsma

[edit] Needs an expert to expand on (1)

In solid mechanics, 'P' means 'load' NOT 'momentum'. And the unit of load 'P' is 'newtons(N)'

ps. unit of impulse : N * m/(s^2) = {kg * m/(s^2)} * s = kg * m/s , unit of momentum : kg * m/s

I've made a number of changes to the page which may hopefully clarify things as well as expand the scope. Please let me know if anyone disagrees or thinks things should be made clearer. -- Kvetner 11:56, 17 October 2006 (UTC)
