🔍 Key Concepts

• Stern tube bearing materials used in traditional and modern ships • How lubrication (oil vs water) affects friction and wear • Properties of lignum vitae, bronze, and hard rubber as bearing materials

💭 Think About

• Think about which material was historically favored for low-friction stern tube bearings, especially in seawater-lubricated systems. • Compare how each choice behaves when wet: does it swell, self-lubricate, or require separate lubrication? • Consider which options are metals versus non-metals, and how that usually affects friction in sliding bearings.

✅ Before You Answer

• Identify which of the options is a naturally self-lubricating material when used in water. • Determine which materials require external oil lubrication to achieve low friction. • Recall which bearing type is traditionally associated with old wooden ships and early steel ships for propeller shafts.
