Quizplus · Accepted Answer

Technician A is correct that extension spindles allow the measurement of cylinder bores as they allow the micrometer to reach deep into the bore. Technician B is also correct that once the micrometer is inserted into the bore and extended, it should be tightened and removed, as this ensures accurate measurement and avoids any damage to the micrometer or the bore. Therefore, both technicians are correct.
