SITUATION 3
Solve the following problems relating to buoyancy:
7. A solid spherical ball with unit weight 8.52 kN/m³ floats in dead
sea (sp. gr. = 1.24). Find the percentage of the volume draft to its
total volume.
a. 72.52%
b. 73.69%
c. 70.04%
d. 68.35%
8. A cube with a side of 550 mm. What force is required to
completely submerged the cube in water if its specific gravity is
0.80?
a. 423.8 N
b. 326.4 N
c. 344.6 N
d. 245.3 N
9. A tank containing water has a total of weight of 75 kg when
weighed. Obtain the new reading on the weighing scale if a 50
mm by 50 mm piece is wood is held vertically in the water to a
depth of 600 mm.
a. 73.5 kg
b. 76.5 kg
c. 77.5 kg
d. 78.5 kg
10. The Mayflower ship having a displacement of 27000 metric tons
and a draft of 10.4 m in ocean (sp. gr. = 1.03) enters in the
Legazpi International Port with a specific gravity of 1.0
(seawater). If Mayflower's horizontal section of the ship at the
waterline is 3000 m², what depth of seawater is required to float
the ship?
a. 10.63 m
b. 10.58 m
c. 10.66 m
d. 10.54 m
