List with zero metacentric height 321
Exercise 38
1 Find the list when a mass of 10 tonnes is shifted transversely through a horizontal distance of 14 m in a ship of 8000 tonnes displacement which has zero initial metacentric height. BM 2 m.
2 A ship of 8000 tonnes displacement has zero initial metacentric height. BM 4 m. Find the list if a weight of 20 tonnes is shifted transversely across the deck through a horizontal distance of 10 m.
3 A ship of 10000 tonnes displacement is ¯oating in water of density 1.025 kg/cu. m and has a zero initial metacentric height. Calculate the list when a mass of 15 tonnes is moved transversely across the deck through a horizontal distance of 18m. The second moment of the waterplane area about the centre line is 105 m4:
4 A ship of 12 250 tonnes displacement is ¯oating upright. KB 3.8 m, KM 8 m and KG 8 m. Assuming that the ship is wall-sided, ®nd the list if a mass of 2 tonnes, already on board, is shifted transversely through a horizontal distance of 12 m.
