Question

I cant see the solution picture to this problem. A rotating door is made from four rectangular glass panes,asshown in the figure. The mass of each pane is 73.3 kg. Apersonpushes on the outer edge of one pane with a force ofF =116 N that is directed perpendicular to the pane.Determine themagnitude of the door's angular acceleration.

Explanation / Answer

The torque acting on the door to make it move is givenas         = R xF It can also be defined as       = 4 I    I is the moment of inertia I = ( 1/3)mL^2 Equating the above equations      4 I = F L       = F L / 4 I          = F L /4 (1/3)mL^2          = F /(4/3)mL         = 116/(4/3)(73.3kg)(1.2m)          = 0.989rad/s^2
