A rectangular raft, 3 m wide, 6 m long and 2 m high floats in water. It has a draught of 1.5 m. Two loads of 900 kg each are then placed on the transverse centre line with their centres of gravity 2 m from each other. Determine: a. The mass of the float. b. The immersion (draught) of the float after it is loaded. c. The metacentric height of the float with a load (assume the gravity of the raft and load coincides with the geometrical centre). d. The angle by which the float will tilt if one mass is placed on the longitudinal centre line.

Question
A rectangular raft, 3 m wide, 6 m long and 2 m high floats in water. It has a draught of 1.5 m.
Two loads of 900 kg each are then placed on the transverse centre line with their centres of
gravity 2 m from each other. Determine:
a. The mass of the float.
b. The immersion (draught) of the float after it is loaded.
c. The metacentric height of the float with a load (assume the gravity of the raft and load
coincides with the geometrical centre).
d. The angle by which the float will tilt if one mass is placed on the longitudinal centre line.
