I don't especially like the term reaction force, but it seems to be very commonly used in the mechanical engineering community to mean exactly what I meant it to mean, which is why I used it. I also dislike the term Newtonian mechanics because Newton had very little to do with much of the...

You stated that in Newtonian mechanics Newton's 3rd law is never violated. This, of course, would seem to be true by definition. However, which version of Newtonian mechanics are you talking about? Newtonian mechanics as originally envisioned by Newton, or the mechanics that evolved through the...

Thank you, Chestermiller, for providing a coherent, intelligible and thorough response to my original post.

I've already addressed this, but it seems that I will need to do so again. There is no such thing as a force that propagates with infinite speed. That is an absolute fact. << Snide comment removed by a Mentor >> The gravitational force and electrical force propagate at the speed of light...

Thank you for your reply. I'm not exactly sure what you're getting at here; the whole point of this is that the applied force is not applied simultaneously at both ends of the object. At the instant the force is applied Newton's 3rd law is violated and the object is not in equilibrium...

This is highly speculative, and I very much doubt that it is actually correct. If anybody knows of a correct equation for time-dependent axial deformation, or at least how to go about deriving a more correct equation, I would greatly appreciate any feedback.

I'm a recent mechanical engineering graduate who started out as a physics major and has a continuing interest in physics.
