Test #2 (Chapter 5 to 7)
1. In this drawing, which datum is secondary? a. A b. B c. C d. None of the above [pic] 2. Based on the drawing, datum B is __________ datum feature. a. A planar b. A centerplane c. An axis d. An invalid [pic] 3. On the drawing, datum feature A consists of ________ surface(s). a. 0 b. 1 c. 2 d. None of the above [pic] 4. Basic dimensions are used to describe datum target locations to reduce gage variation. T or F 5. A datum target should not be used when the part may rock or wobble when the datum feature contacts the datum plane. T or F 6. A datum target area may be simulated in the gage by using a __________ gage pin. a. pointed b. concaved c. flat-tipped d. spherical-tipped 7. When a planar feature of size is referenced as a datum feature reference, it results in a _________ as the datum. a. Feature of size b. centerplane c. virtual condition d. feature 8. Based on the drawing, datum C is __________ datum feature. a. An axis b. A planar c. A centerplane d. An invalid [pic] 9. When a feature of size is used as a datum feature, the resulting datum is _________. a. A plane or point b. An axis or centerplane c. A line or point d. planar 10. When a feature of size datum feature is referenced at MMC, the part may be loose (shift) in the gage. T or F 11. The datum feature simulator for datum A is fixed in size. T or F [pic] 12. In this example, the datum feature simulator for datum B is. . . a. Not needed b. an adjustable pin c. a 10.0 diameter pin d. the virtual condition of diameter B [pic]
