🔍 Key Concepts

• Journal bearings and how the shaft (journal) sits in the bearing when there is no rotation • Effect of gravity and load direction on the journal position when the oil wedge is not developed • How the oil film shifts the journal away from the load side only when the shaft is turning

💭 Think About

• When the shaft is stopped, where does the weight of the shaft and load naturally push the journal inside the bearing shell? Top, bottom, or side? • In a running condition, the journal rides on a wedge of oil opposite the direction of rotation. If you remove that wedge (shaft stopped), where would metal-to-metal contact logically occur? • Look at the arrows showing direction of rotation in each figure: which one shows the journal located where it would be supported directly by the bearing under gravity with no hydrodynamic lift?

✅ Before You Answer

• Identify which part of each sketch is the bearing shell and which is the journal (shaft) • Determine the direction of rotation from the arrow and imagine where the oil wedge would be when running; then remove that wedge in your mind for the stopped condition • Before choosing, verify that your figure shows the journal sitting on the lowest point of support in the bearing, not being lifted away from it
