🔍 Key Concepts

• Look at how the small pinions mesh with the large gears in a double‑reduction gear train • Understand the difference between a pinion (small driving gear) and a gear/wheel (larger driven gear) • Know which elements are associated with the high‑speed shaft (turbine side) and which are on the low‑speed shaft (propeller side)

💭 Think About

• Trace the power flow: from the turbine (highest speed) down to the propeller (lowest speed). Which labeled element would logically be closer to the propeller in that sequence? • Compare the diameters of the components: which labeled parts look like main reduction gears and which look like pinions? • Ask yourself: in a double‑reduction setup, where would the first reduction occur, and where would the second reduction occur relative to the large bull gear at the bottom?

✅ Before You Answer

• Confirm that label III is pointing to a small gear on an intermediate/low‑speed shaft, not the large main gear • Identify which component (by location and size) is clearly the second reduction gear (the very large bull gear) to eliminate that option • Make sure you distinguish between high‑speed pinion (nearest the turbine, smallest and highest in the train) and any lower‑speed pinion that meshes with the big bull gear
