A crane lifts the 23000 kg steel hull of a ship out of the water. Determine the following.
(a) the tension in the crane's cable when the hull is submerged in the water
Physics: Buoyancy -
When submerged, the buoyancy force equals the weight of water being lifted with the ship. Therefore the cable tension force is the hull Weight, M g = 2.25*10^5 Newtons
