A 24 kg solid door is 220 cm tall, 95 cm wide. What is the door's moment of inertia for rotation about a vertical axis inside the door, 17 cm from one edge?
I've looked at examples of how to do this problem. They connect it to center mass but I get confused when determining what the center mass is. They also talk about parallel axis theorem, but my professor has not introduced this approach.
The formula that I have been using is I= (1/3)mr^2
