The maximum diameter of the device...

🔍 Key Concepts

• Carefully distinguish between diameter and length dimensions on a mechanical drawing • Identify which view (end view vs. side view) clearly shows the largest circular outline of the shaft • Note that some dimensions on the drawing are for features (threads, holes, undercuts) and not for the overall size

💭 Think About

• In which view can you actually see the full round shape of the device and therefore its true outside diameter? • Look at all the dimension callouts that use inches—which of them are clearly labeled across the widest circular part, and which run along the shaft length? • Among the answer choices, which value matches the dimension that points to the outermost circle in the end view, not to a hole, thread, or length segment?

✅ Before You Answer

• Verify which dimension arrow touches the outer circle in the end view, not the inner circles or drilled holes • Confirm that the dimension you select is measured across the part (side‑to‑side) rather than along the shaft (end‑to‑end) • Double‑check that your number is not associated with a drill size, thread size, or length note but with the main body diameter of the shaft
