Hello everyone, Since yesterday i'm struggling with concept of CoG and of course in CoM. The problem is that I don't understand why lower to the ground CoG is more stable then CoG more off the ground. On the internet there is batch of information about that but nobody explained it by momentum equlibrium. And that's what I need to understand that because of course i feel that but when i trying to do moments of equilibrium then i don't see this dependence. For example two drawings: From the Moments around the point called "Tilt axis" I compute the equation: Fl = Wb/2 in both case and I see the depend on the base rather then position of CoG. Can someone explain my what I do wrong? Should I point the force that i attached as a pulling one to the CoG? But it will make no sense from my point because it's like open a door lever task. If i will need to move the force to CoG i will generate less moment and door shouldn't open. It's make my head blow up. Could someone help me to understand where is mistake? I also trying to understand why we put sometimes force (not only the weight of itself) in CoG and when we should?
