Determine the magnitude of the door's angular acceleration.?

Question

A rotating door is made from four rectangular glass panes, as shown in the drawing. The mass of each pane is 93 kg. A person pushes on the outer edge of one pane with a force of F = 60 N that is directed perpendicular to the pane. Determine the magnitude of the door's angular acceleration.

Answer 1

Τ = Iα
T = 60W
I = 4*93*W/2
α = 2*60W/(4*93W)
α = 0.32258 rad./s
