Consider a fever thermometer that contains 0.01 cm³ of mercury, Find the diameter of the capillary if a 1 C° change corresponds to a level change of 0.5 cm . Assume the glass does noe expand.
A fit or assembly of pin and hole is designated by 55mm H9/d9/
a) Describe what kind of fit it is.
b) Find: i)tolerances for pin & hole ii) Deviations (Upper, Lower and Fundamental) for both hole and pin
iii) The maximum, minimum, mean and most frequent clearances.(hint: mean is the most frequent value
in normal distribution)
c) Neatly sketch the fit/assembly in a graph paper and show all the pertinent dimensions
d) Assume the natural spread and tolerance coincide for both shaft and hole. What % of fit was less than
the minimum clearance?
(find σ for shaft, hole and clearance. For the σ of clearance, use the population combination formula
mentioned in the study material named statistical considerations)
