1. A bronze sleeve bearing is to be press fit into the joint hub. The nominal size of the outside diameter of the bearing and the inside diameter of the hub is 7/8”. What should be the tolerances for the outside of the bearing and the inside of the hub if a FN4 force fit is desired? 2. A roller bearing is to be pressed into a wheel hub. The nominal outer diameter of the bearing and the inner diameter of the hub is 58 mm. What should be the tolerances for the outer diameter of the bearing and the inner diameter of the hub if a shaft basis medium drive fit is desired? Do not switch to a preferred size. Questions 3 through 10 relate to the drawing sheet. 3. Draw and label the datums on the figure to the right. 4. What is the LMC of peg 3? 5. What is the maximum possible distance between the centers of pegs 2 and 3? Name:
6. You are inspecting a fabricated part. The diameter of hole 1 is measured as ?.48 inches. The center of the hole is .995 inches from datum A as seen in the top view. What is the maximum distance that the center of the hole be from datum B as seen in the top view so that this feature will meet its specification? 7. What is the closest allowable distance between points 1 and 2 as seen in the top view? 8. What is the perpendicularity tolerance of peg 1 if it is made with a diameter of .21 inches? 9. What is the maximum possible distance between the center of peg 1 and datum B as seen in the front view? 10. You are inspecting a fabricated part and you measure the diameter of peg 1 as ? .22 inches. The center of the hole is a distance of .019 inches from the ‘perfect’ location. You’ve determined that this feature does not meet its specification. What would be a practical way that this feature could be modified so that it will meet its size and position specifications?
