The ship with a displacement of 2500 ton with a draft of 5 m has a metacentric height of 0.4 m. Determine how much you need to take in ballast compartment, the center of gravity of which is separated from the main line at 0.4 m to increase the metacentric height of 0.5 m ~.
We introduce the notation:
Displacement D = 2500ts
Draught T = 5 m
Metacentric height h0 = 0.4m
Metacentric height after moving the ballast m h1 = 0,5
