a.  When checking a ball joint the dial moves between these two points.  The tolerance is .024”.  Is this in spec?  If not, how much is it out of tolerance?

b.  The tolerance is 1/64".  Is this in spec?  If not, how much is it out of tolerance?

Solutions:

a.  The dial moved 0.030" and the tolerance is 0.024".
It is out of spec by (0.030" – 0.024" = 0.006) = 0.006"

b.  A tolerance of 1/64" equals 0.015625".
It is out of spec by (0.030000" –- 0.015625") = 0.014375"
