A solid cylinder of diameter 4.5 has a height of 2.5 metres. Find the meta-centric height of the cylinder when it is floating in water with its axis vertical. The sp. gr. of the cylinder=0.45. Correct Answer 1.9 m

n:BG= Centre of pontoon – Centre of immersed portion=1.25-0.45*2.5=0.125 Metacentric height=I/∀ -BG I=π*r⁴ ∀= π*r*r*h Metacentric height=1.9 m.
