In the fit below, the Hole Diameter at LMC would be:

Solution

For reference data, I have used the ANSI table for limit and tolerance \"Table 9: ANSI Standard Force and Shrink Fits

ANSI B4.1-1967 (R1987)\"

FN2 is a medium class of \"Force Fit\" also called Medium drive fit.

Referring to the ANSI table, for the given value of nominal diameter of 1.250\" FN2 fit.

Upper limit for hole = +0.001\"

Lower limit for hole = 0

That is Maximum hole size = 1.250 + 0.001 = 1.251\"

and Minimum hole size = 1.250 + 0 = 1.250\"

For Least Material Condition (LMC) we take the maximum hole size.

So the answer is 1.251 inch.
