For a bicycle, the nominal diameter of the outer race of a ball bearing and the inner surface of the hub is 62 mm. What should be the maximum dimension for the outer race of the ball bearing if a medium drive hole basis fit is desired? Use a preferred fit.

As medium drive hole basis fit is desired ,the general condition of choosing the type of fit as given below from figurehence Interference fit H7/u6 is being choosen

outer race of bearing acts as hole so the lower limit of outer race will be the nominal size and tolerance will be take from table below for nominal diameter 62 mm

Minimum size= 62mm

Maximum size= 62+0.030=62.030mm

The existing record shows machine bearing has a mean diameter of 0.6 inches. Bearing diameter is known to be normally distributed with standard deviation σ = 0.1 inches. (Additional note: If the mean diameter of bearings is larger or smaller than 0.6 inches, then the process is out of control and must be adjusted.) A random sample of 60 bearings are selected, and the average diameter of the bearing from this sample is 0.55 inches. Use α=0.02 to test the...
