I have this door that was designed to supposedly open for 180 degrees in 1 second. A Pneumatic Plunger was used to push the door. However I'm not sure if this was strong enough to open the door. Can this be counted as Partially Inelastic Collision? DOOR: m = 136pound width = 40 inch height =...

the axis of rotation is the end of the door on the right side

Thank you very much for your help. I kept struggling with finding the torque, using a different equation. That mass moment of inertia is going to help me a lot

I'm trying to find a gearmotor that applies enough torque to close this door. Door Mass = 136lbs Door Dims = 40in width x 85in height Time to close = 60sec Door's rotation = 180 degrees Any tips and advice would truly be appreciated.
