(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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)

2. Relevant equations

I used the following equations:

⅀F_{x}=ma_{x}

⅀F_{y}=0

⅀M_{G}=0 (since rod is in translation)

3. The attempt at a solution

The results i arrived at are:

θ = 33.4°

a = 15m/s^{2}

My question is, there exists a moment about point A (point of contact between bar and contact surface) equal to 8.26Nm. What is the physical meaning/significance of this moment? Would not the rod rotate about A due to this moment? Requesting for help please.

If my question has already been discussed earlier, request some of you to give link to those threads.

Thanks in advance.
