Falling Dumbbell: Determine Force vs Angle

[sergiokapone]

This is not the same as the force along the bar.

Yes, I understand.
Correct equation is
$2m\vec a_{ CM}=2m\vec g +\vec N_1 + ⃗\vec N_2$
$\vec N_1$ - is the reaction from the floore
$\vec N_2$ - is the reaction from the wall
Also, I know from the energy law conservation or other the normal and tangential accelerations of the CM. How I can find $N_2$, I need $a_x$?
