Inclined Bar Translation: Understanding the Physical Meaning of Moments

AI Thread Summary
The discussion centers on the analysis of a homogenous slender bar being pushed along a horizontal surface by a force, with a focus on the angle of translation and the resulting acceleration. The calculated angle of inclination is 33.4°, and the acceleration is determined to be 15 m/s². A moment of 8.26 Nm is identified about point A, raising questions about its physical significance and whether it would cause the rod to rotate around point A. The inquiry seeks clarification on the implications of this moment in the context of pure translation. Understanding the relationship between force, moment, and motion is crucial for accurate analysis in mechanics.

I have a question on pure translation of inclined bar. The problem statement is:
A homogenous slender bar with a mass of 4 kg and a length of 500mm being pushed along the smooth horizontal surface by a horizontal force P=60N. Determine the angle θ for translation. What is the accompanying acceleration? (FBD and kinetic diagram attached)

I used the following equations:
⅀Fx=max
⅀Fy=0
⅀MG=0 (since rod is in translation)
The results
θ = 33.4°
a = 15m/s2
My question is, there exists a moment about point A equal to 8.26Nm. What is the physical meaning of this moment? Would not the rod rotate about A due to this moment? Requesting for help please.

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
