Reference Answer
### (a) Explanation of Framing Systems
#### 1. Transverse Framing (Isherwood System)
This is a traditional method of ship construction where the primary structural members are oriented in the transverse (athwartships) direction.
* **Concept**: The hull is constructed from a series of strong, closely-spaced transverse rings that provide the primary resistance to hydrostatic pressure, local cargo loads, and stresses from rolling and dry-docking.
