Stability considerations are important for both floating or neutrally buoyant/ suspended bodies because the centers of gravity and buoyancy do not necessarily coincide. Furthermore, the vertical alignment of the line of action of the buoyant force and the line of action of the weight of the body (i.e., zero moment) provides the basis for determining the stability (stable equilibrium) of a floating or a neutrally buoyant body. (a) Explain what happens when a small rotation causes the two centers to move out of vertical alignment. (b) Explain what happens when a small rotation does not cause the two centers to move out of vertical alignment.
