A rotating door is made from four rectangular glass panes, as shown in the drawing. The mass of each pane is 95 kg. A person pushes on the outer edge of one pane with a force of F = 80 N that is directed perpendicular to the pane. Determine the magnitude of the door's angular acceleration.

** the width of pane to the rotating axis is 1.2m

I don't have access to the drawing. You have to determine the total moment of inertia. If the panes go to the center, then Itotal= 4Ipane
and I pane is the same as a rod rotating about its end.

Then,

Torque=Itotal*acceleration.
I will be happy to critique your work. I avoid doing students homework for them.
