🔍 Key Concepts
• Study the parts list table next to the illustration and locate the word Rotor in the NAME column.
• Compare the material column for the rotor parts with the materials listed in the answer choices.
• Notice which materials in the table are used for bearings, nameplates, and special corrosion‑resistant parts versus the main rotating element.
đź’ Think About
• Which part numbers in the drawing are labeled as rotors, and what material is specified for them in the table?
• Do any of the options (Monel, brass sheet, bearing bronze, steel) appear to be used mainly for small fittings or plates rather than the primary rotor?
• If more than one rotor is listed (for example, power and idler), do they share the same material, and which option matches that material?.
âś… Before You Answer
• Make sure you are reading the exact line in the table that corresponds to the rotor (e.g., Power Rotor or Idler Rotor).
• Confirm that the spelling of the material in the table exactly matches one of the four choices.
• Verify that you are not confusing the rotor material with nearby items like bearings, spacers, or name plates, which use different metals.
