Note that the micrometerreads in hundredths of millimeters. Adjust K so thatthe micrometer will stand at zero when the sounderclicks. After this adjustment do not allow the jacketto turn, otherwise it will affect the reading of themicrometer. Now turn back the micrometer so thatit will be out of the way when the rod expands. Tak
