🔍 Key Concepts

• Hydrodynamic lubrication depends on a converging wedge of fluid between surfaces • A pressure-generating film needs relative motion AND the right geometry of the gap • Think about how parallel vs. nonparallel and curved surfaces affect fluid thickness

💭 Think About

• Which surface combinations create a wedge-shaped clearance where the fluid thickness changes from thick to thin along the direction of motion? • If the gap thickness is the same everywhere between two surfaces, what happens to pressure buildup in the fluid film? • How do curvature and nonparallel alignment influence the ability of the fluid to be dragged in and squeezed to form a lifting pressure?

✅ Before You Answer

• Identify which surface type gives a constant film thickness along the direction of motion • Ask: For each choice, can a converging wedge form under load and motion? • Eliminate any option where geometry makes it impossible to develop load-carrying hydrodynamic pressure in the film
