Question

Which one of the following statements is TRUE?

Correct answer (C) The 'GO' gage controls the lower limit of a hole Solution In limit gauging, the 'GO' and 'NO GO' gages are designed based on the Maximum Material Condition (MMC) and Least Material Condition (LMC): 1. For a Hole: MMC is the minimum diameter (lower limit). The 'GO' gage must be able to enter the hole at its smallest allowable size. Thus, the 'GO' gage controls the lower limit of a hole. LMC is the maximum diameter (upper limit). The 'NO GO' gage should not be able to enter the hole. Thus, the 'NO GO' gage controls the upper limit of a hole. 2. For a Shaft: MMC is the maximum diameter (upper limit). The 'GO' gage (ring or snap) must pass over the shaft. Thus, 'GO' controls the upper limit of a shaft. LMC is the minimum diameter (lower limit). The 'NO GO' gage should not pass. Thus, 'NO GO' controls the lower limit of a shaft. Therefore, statement (C) is the only true statement.
