Answer is:
25.00 mm
Explanation:
A dimension is stated as Dia 25 H7 in a drawing. The lower limit is 25.00 mm.
For 25 H7 Tolerance Grade
Basic Size = 25.000 mm
ES = +21 Microns = 0.021 mm
EI = 0 Microns = 0.000 mm
Hence
Lower limit = Basic Size + EI = 25.000 + 0.000 = 25.000 mm
Upper Limit = Basic Size + ES = 25.000 + 0.021 = 25.021 mm
Hence A dimension is stated as Dia 25 H7 in a drawing. The lower limit is 25.000 mm.
Answer is:
0.04 mm
Explanation:
A dimension is stated as 25 +/-0.02 mm in a drawing. Then
Basic Size = 25.000 mm
Upper Tolerance = + 0.02 mm
Lower Tolerance = - 0.02 mm
Total Tolerance = 0.02 + 0.02 = 0.04 mm
Answer is:
Tolerance
