Study Notes
Shear Force and Bending Moment Diagram
- Load curve represents the distribution of weight along the ship's length
- Light displacement = (L x B x D) x density = 2400 tonnes
- Light displacement / length overall = 40 t/m (on lightweight)
- Cargo equally distributed in CH#2 (Trimmed): 120 tonnes / 20m = 6 t/m (on deadweight)
- Load displacement = light displacement + load weight (or deadweight) = 2520 tonnes
- Load displacement / length overall = 2520 t / 60 m = 42 t/m (on buoyancy)
Stress Tables and Ship Stability
- Stress tables represent the relationship between applied stress and corresponding deflection of the ship's hull
- Used to assess a ship's structural integrity and stability under various loading conditions
- Essential tool for naval architects and engineers to ensure ship's structure remains within safe limits during operation
- Typical stress table contains information about ship's structural members (frames, bulkheads, decks, hull plating) and maximum allowable stresses or loads
Beam Theory and Bending of Ships
- Bending of ships likened to bending of beams
- Calculating necessary strength of ships made difficult by varied forces (statical and dynamical)
- Statical forces include weight of structure, buoyancy forces, hydrostatic pressure, and concentrated local weights
- Dynamical forces include pitching, heaving, and rolling due to wind and waves
