Reference Answer
### (a) Static Stresses on a Vessel at Rest in Still Water
Static stresses are those forces and moments acting on a ship's hull when it is floating in calm, still water. They arise primarily from the non-uniform distribution of weight (acting downwards) and buoyancy (acting upwards) along the length of the vessel.
#### 1. Longitudinal Bending Stresses (Hogging and Sagging)
These are the most significant static stresses, acting along the length of the ship's hull girder.
