Multiple choice

What are the upper and lower limits of the shaft represented by 60 f8? Use the following data: Diameter 60 lies in the diameter step of 50-80 mm Fundamental tolerance unit, i, in $\mu$m = 0.45D1/3+0.001D, where D is the representative size in mm; Tolerance value for IT8=25i. Fundamental deviation for 'f' shaft = -5.5D0.41

  1. Lower limit = 59.924 mm, Upper Limit = 59.970 mm

  2. Lower limit = 59.954 mm, Upper Limit = 60.000 mm

  3. Lower limit = 59.970 mm, Upper Limit = 60.016 mm

  4. Lower limit = 60.000 mm, Upper Limit = 60.046 mm
