Why does a translating inclined bar have a moment about point A?

[mkkeyan]

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:
⅀F_x=ma_x
⅀F_y=0
⅀M_G=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.

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