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
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
