🔍 Key Concepts

• Carefully study section A-A of the thrust bearing where the tilting pads (thrust shoes) are visible around the shaft • Each thrust shoe is one separate sector-shaped pad that actually takes thrust load, not the thin ribs or frame behind them • Think about the full 360° circle: how many identical sector pads are shown, and is any part of the circle hidden or cut away in the drawing?

💭 Think About

• In view A, how many distinct sector-shaped pads can you see making contact (or potential contact) with the thrust collar on the shaft? • If you imagine rotating one pad around the shaft, how many of those pads would fit evenly around the full circle based on the angle each pad subtends? • Are you accidentally counting support ribs, or are you correctly counting only the load‑carrying pads that form the bearing surface?

✅ Before You Answer

• Be sure you are counting only the tilting thrust shoes (the broader arc-shaped pads), not the narrow support arms or webs behind them • Confirm that you’ve accounted for the entire circumference – check whether the drawing shows all pads or if the symmetry lets you infer the total number • Double-check that your count matches one of the choices 6, 10, 12, 20 before deciding.
