Reference Answer
### (a) Static Stresses on a Vessel at Rest in Still Water
Static stresses are those imposed on a ship's structure when it is at rest in calm water. They arise from the distribution of weight (W) and buoyancy (B) and the effect of hydrostatic pressure.
**1. Longitudinal Bending Stresses (Hogging and Sagging)**
These are the most significant static stresses and act along the length of the ship's hull girder. They are caused by inequalities in the longitudinal distribution of weight and buoyancy.
