Let's analyze the question step by step: ### Given Data - **Bearing internal diameter**: \( 50^{+.03}_{-.01} \) mm (means it can vary from 49.99 mm to 50.03 mm) - **Shaft diameter**: \( 50^{+.01}_{-.05} \) mm (means it can vary from 49.95 mm to 50.01 mm) ### Clearance Calculation **Clearance** = Bearing inner diameter - Shaft outer diameter #### **Maximum clearance:** - Max bearing diameter = 50.03 mm - Min shaft diameter = 49.95 mm - Max clearance = 50.03 - 49.95 = **.08 mm** #### **Minimum clearance:** - Min bearing diameter = 49.99 mm - Max shaft diameter = 50.01 mm - Min clearance = 49.99 - 50.01 = **-.02 mm** (This is an interference, not clearance!) #### Check the provided options: - .45 mm and .1 mm - .1 mm and .45 mm - None of the above - .1 mm and .35 mm None of these match the calculated values (**.08 mm** and **-.02 mm**). ### **Correct Answer:** #### **None of the above** --- **Summary Table:** | Condition | Value (mm) | |-----------------------|------------| | Maximum clearance | .08 | | Minimum clearance | -.02 | **So, the correct option is:** **None of the above**
