Given information

Given values:

The steel shell is kg in weight.

Formula used:

The weight of the steel hull when fully submerged in water is equal to the sum of tension and water buoyant force, .
 
Tension, mass, and buoyant force are represented by the letters , , and  , respectively.
 
As a result, the appropriate formula is
 
The stress equals the weight when the hull is totally submerged.

Step-by-step explanation

Step 1.

When an object is submerged in a fluid, the fluid exerts a buoyancy force on the object. This force is directed upward and is proportional to the volume of fluid buried beneath it.
