A crane lifts the 18,000kg steel hull of a ship out of the water.
The density of steel is known to be 7.8 x 103 kg/m3, while that of water is 1000 kg/m3.
A) While the steel hull is fully submerged in the water, what is the volume of water displaced by the hull? I really have no idea how to work this problem out.
Buoyancy = m* density * V displaced * G
m=pv
B) What is the tension in the crane's cable when the hull is fully submerged?
I believe this one is related to A
Density * Volume * G = F m=(density) Volume
1000* 18000/10 *10
f=1.8 x 107
C) What is the tension in the crane's cable when the hull is out of the water?
Ft= mg
Ft = 18,000 * 10 (class standard)
Ft= 180,000N
