I asked you to make a report and this was your answr but I want you to complite it casue you didn't 
1. Introduction:
As a marine engineer, understanding the structural forces that affect ships and implementing comprehensive preventive measures is paramount to ensure the safety, durability, and longevity of ship structures. This report will focus on analyzing the primary structural forces acting on ships and propose detailed prevention methods to safeguard ship structures, highlighting the crucial role of marine engineers in ensuring ship integrity.

2. Longitudinal Forces:
2.1. Bow Thrust and Stern Thrust:
Bow Thrust:
- Bow thrust, generated by the ship’s bow propeller, plays a crucial role in a ship’s forward propulsion.
- Marine engineers closely analyze the propeller’s design, considering factors such as blade shape, diameter, and pitch, to optimize thrust efficiency.
- Additionally, they monitor and evaluate the propeller’s performance through regular inspections and testing, ensuring its alignment and integrity.

Stern Thrust:
- Stern thrust, generated by the stern propeller, contributes to maneuvering and reverse propulsion.
- Marine engineers pay careful attention to the stern thruster’s design and alignment to prevent excessive forces that may affect the ship’s structure.
- Thorough inspection, maintenance, and performance testing of stern thrusters are conducted to detect potential issues and ensure their optimal operation.

2.2. Resistance:
- Resistance force opposes the ship’s forward motion, subjecting the hull to significant stresses that can impact both fuel efficiency and structural integrity.
- Marine engineers employ advanced hydrodynamic analysis and computational fluid dynamics (CFD) simulations to optimize hull design and minimize resistance.
- They collaborate with naval architects to select appropriate materials with high tensile strength and corrosion resistance, ensuring the ship’s structural integrity is not compromised by prolonged exposure to resistance-induced forces.

2.3. Dynamic Forces:
Waves:
- Waves exert dynamic forces on a ship’s structure, impacting its stability and integrity.
- Marine engineers employ advanced structural design techniques, including finite element analysis (FEA), to assess and ensure the ship’s ability to withstand wave-induced loads.
- They also collaborate with naval architects to identify critical structural components that require reinforcement or the integration of wave-damping systems to mitigate the effects of waves.

Water Currents:
- Water currents can impose additional stresses on a ship’s hull and appendages, particularly during mooring or when operating in narrow channels.
- Marine engineers consider the ship’s design, such as the alignment, strength, and size of the hull, rudders, and propellers, to minimize the impact of water currents.
- They participate in the calculation of load distributions and draft adjustments to optimize the ship’s performance under various current conditions.

3. Transverse Forces:
3.1. Rolling Forces:
- Rolling forces caused by waves striking the ship’s sides laterally can lead to significant structural stresses and instability.
- Marine engineers collaborate with naval architects to design ships with optimal stability characteristics,
