  • (A) parkson gear tester
  • (B) tooth caliper
  • (C) base pitch measuring instrument
  • (D) involute profile testing machine

✅ Correct Answer: (A) parkson gear tester
Explanation: rolling test is generally performed on parkson gear tester. this test reveals any errors in pitch, tooth form and concentricity of pitch line. any of the above errors will cause the variation of centre distance, when two gears are in mesh with each other.
