🔍 Key Concepts

• Purpose of lubrication on moving mechanical parts like winches and davits • How friction, corrosion, and moisture affect metal components over time • Typical failure modes of poorly maintained lifeboat launching systems

💭 Think About

• Think about what happens to metal parts that move, rotate, and bear loads when they are not lubricated over weeks and months. • Consider which of the listed problems are realistically connected to reduced lubrication film between metal surfaces. • Ask yourself: does poor lubrication affect only one component, or can it lead to several different types of damage in the system?

✅ Before You Answer

• For each option, ask: Is this a direct or indirect consequence of insufficient lubrication? • Consider whether corrosion, freezing, or moisture intrusion can be made worse when lubricant is missing or degraded. • Verify which of the listed issues would prevent safe and smooth operation of lifeboat winches and davits in an emergency.
