What sizes of gage pins would a machinist need for a dimension of 3/32 ± 1/64th inches for a go/no go gage setup (rounded to three places)?

What sizes of gage pins would a machinist need for a dimension of 3/32 ± 1/64th inches for a go/no go gage setup (rounded to three places)?

• A. 0.110/0.078
• B. 0.120/0.090
• C. 0.115/0.080
• D. 0.125/0.085

Answer: (A)

To find the correct sizes of gage pins needed for a dimension of 3/32 ± 1/64 inches, you start by converting the fractions to decimal form for easier calculations. First, convert 3/32 to decimal: - 3 divided by 32 equals 0.09375. Next, calculate the plus and minus tolerances. The tolerance is ± 1/64 inches: - Convert 1/64 to decimal, which is approximately 0.015625. Now, compute the upper and lower limits: - Upper limit: 0.09375 + 0.015625 = 0.109375 - Lower limit: 0.09375 - 0.015625 = 0.078125 This means the range for the acceptable dimensions is from 0.078125 to 0.109375. Now, rounding these values to three decimal places: - The lower limit rounds to 0.078 and the upper limit rounds to 0.110. Therefore, the gage pins required for a go/no go gage setup are 0.110 for the upper limit and 0.078 for the lower limit. The choice of 0.110/

To find the correct sizes of gage pins needed for a dimension of 3/32 ± 1/64 inches, you start by converting the fractions to decimal form for easier calculations.

First, convert 3/32 to decimal:

• 3 divided by 32 equals 0.09375.

Next, calculate the plus and minus tolerances. The tolerance is ± 1/64 inches:

• Convert 1/64 to decimal, which is approximately 0.015625.

Now, compute the upper and lower limits:

• Upper limit: 0.09375 + 0.015625 = 0.109375

• Lower limit: 0.09375 - 0.015625 = 0.078125

This means the range for the acceptable dimensions is from 0.078125 to 0.109375.

Now, rounding these values to three decimal places:

• The lower limit rounds to 0.078 and the upper limit rounds to 0.110.

Therefore, the gage pins required for a go/no go gage setup are 0.110 for the upper limit and 0.078 for the lower limit.
