### (a) Water Pressure Loads on the Ship's Hull
Water pressure on a ship's hull gives rise to several distinct types of loads and stresses that the structure must be designed to withstand. These can be categorized as hydrostatic, hydrodynamic, global, and local loads.
1. **Hydrostatic Pressure & Buoyancy:**
* At any point on the submerged hull, water exerts pressure that increases linearly with depth, according to the formula $$ P = \rho g h $$, where $$ \rho $$ is the density of water, $$ g $$ is the acceleration due to gravity, and $$ h $$ is the vertical depth below the surface.
