Write a conclusion and recommendation regarding the experiment given below.

Buoyancy and Stability of Floating Object
I.
Introduction
Floating bodies are special case; only a portion of the body is submerged, with
the remainder poking of the free surface. The buoyancy, FA , which is the weight
of the displaced water, i.e., submerged body portion, is equal to its dead weight,
Fa. The center of gravity of the displaced water mass is referred to as the center
of buoyancy, A and the center of gravity of the body is known as the center of
mass, S. In equilibrium position buoyancy force, FA, and the dead weight, FG,
have the same line of action and are equal and opposite. A submerged body is
stable if its center of mass locates below the center of buoyancy. However, this
is not the essential condition for stability in floating objects.
