Hi,
As shown in the attachment, the different situations that occur in an object with 1. the CG above the Centre of buoyancy (CB) and 2. CG below the CB are shown.
A. It is said that the more stable state is when CG is below CB...however, I don't understand this point, since as seen in the figure, in both cases, there is a net moment that seems to tip the boat over.
B. Also, what is the significance of the metacentre?
