Q1. A ship floats at a draught of 10 m In sea water of density 1025 kg/m3.
In this condition the centre of gravity is 9.896 m above the keel and the second moment of area of the waterplane about the centreline Is 94030 m4.
Values of tonne per centimetre Immersion (TPC) in sea water are given in
A load is to be discharged from the ship's centreline by the ship's own heavy lift crane. The Crane head is 12 m above the original centre of gravity of the load and 16 m from the centreline of the ship when swung out. During the discharge it is required that the metacentric height of the ship should not be less than 1.75 m. Calculate EACH Of the following:
(a) the maximum load the crane may lift; (14)
(b) the angle to which the ship will heel when discharging the maximum load. (2)
