2) Assume the small end of the part shown below has a basic bore diameter of 0.25 Inches. We want to assemble the part with a pin with a basic shaft diameter of 0.25 inches, ensuring that the fit between the two parts is a running fit. If we determine that the optimal clearance between the two parts is 0.0009", but no larger than 0.0017", what Class fit would you specify on the drawing? Also calculate the minimum and maximum clearance allowed for this fit class. See Appendix A-1 (25 pts) Class MMC LMC Hole Minimum Clearance Shaft Maximum Clearance
