A pulley is designed to fit on a 90mm diameter shaft with a medium drive fit.

This results in a fit between the hole in the pulley and the shaft being changed to a close running fit.
a) Explain the changes in the tolerance of both shaft and hole, and give an
indication of what this means to the manufacture of the parts.
