🔍 Key Concepts

• Understand what thrust is in a marine propulsion system (which way the force is going) • Know the role of a thrust bearing in relation to the propeller shaft and the ship’s structure • Distinguish between components that handle propeller thrust, engine power transmission, and vibration/shock absorption

💭 Think About

• Ask yourself: Where does the propeller’s pushing force ultimately need to go so the vessel actually moves? Through which part is that force carried into the hull? • Which component’s main job is to carry axial force (along the shaft) rather than just support the shaft radially (up/down) or absorb vibration? • Look at each option and decide: Is this describing force from propeller to ship, from engine to propeller, or just damping movement/shock?

✅ Before You Answer

• Identify which option mentions transmitting propeller thrust into the vessel’s structure, not just between machinery parts • Eliminate choices that mainly describe vibration or shock absorption rather than continuous axial load carrying • Make sure the function you pick matches a bearing that is mounted to the hull/structure to take axial load from the shaft
