🔍 Key Concepts

• Gear ratios and rotational speed relationships between meshed gears • How the camshaft speed compares to crankshaft speed in a four‑stroke diesel engine • Whether components share the same shaft or gear as device B, such as parts labeled 10, T, and N

💭 Think About

• Trace the power flow from the crankshaft up through the gear train: which gear actually drives device B? • Compare the number and arrangement of gear teeth or gear sizes between B and the other labeled parts—what does that tell you about relative speeds? • Look carefully at whether T, N, or 10 are on the same shaft, same gear, or driven by an intermediate gear that would change speed or direction

✅ Before You Answer

• Identify which shaft or gear device B is mounted on and what drives that shaft • Confirm whether device 10 is directly geared to the camshaft or to an intermediate idler gear • Verify if devices T and N are rigidly connected to device B (same shaft) or only share the same housing but different rotating elements
