A cylindrical buoy, shown in Fig.
P3,1.8m
in diameter, 1.2 m high and weighing 10 kN floating in salt water of density
1025k(g)/(m^(3))
. Its centre of gravity is 0.45 m from the bottom. If a load 52 kN is placed on the top, find the maximum height of centre of gravity of this load above the bottom, if the buoy is to remain in stable equibrium.
