Q. What is mean clearance?

  • (A) maximum size of hole minus maximum size of shaft
  • (B) minimum size of hole minus minimum size of shaft
  • (C) mean size of hole minus mean size of shaft
  • (D) average of both size of shaft and hole

✅ Correct Answer: (C) mean size of hole minus mean size of shaft
Explanation: statistical approach allows wider tolerances compared to complete interchangeability approach. methods used by statistical approach are usually permits cheaper production. mean clearance is equal to (mean size of hole – mean size of shaft).
