Question

1. identify the parts of the machinists vise illustrated below. 32. the jaws of a machinist vise are made from hardened steel and have a rough gripping surface. delicate parts can be clamped safely in the jaws by using soft __ . 33. when using a vise to hold a part for sawing or filing, the part should be adjusted so the work is done to the vise jaws to minimize vibration. 34. a safety cleaning tank should be filled with a(n) , . 35. some cleaning tanks are equipped with a(n) , which automatically closes the lid in case of fire. 36. when servicing small gas engines, accurate measurements must be made to determine whether components are within . 37. label the parts of the micrometer illustrated below. 38. a(n) micrometer should be used to measure the outside diameter of a piston or valve stem. 39. to measure the diameter of a cylinder, you should use a(n) micrometer. 40. how does temperature affect a micrometer? 41. before using a micrometer, it should be tested for proper __.

Explanation:

1. Without seeing the actual labeled parts clearly, it's impossible to name them precisely. However, common parts of a machinist's vise include the fixed jaw, movable jaw, screw, and base.
2. Delicate parts can be clamped safely in the jaws by using soft copper or aluminum jaws or soft - jaw inserts to prevent damage.
3. When using a vise for sawing or filing, the part should be adjusted so the work is done as close as possible to the vise jaws to minimize vibration.
4. A safety cleaning tank should be filled with a non - flammable solvent.
5. Some cleaning tanks are equipped with a fire - actuated lid - closing device which automatically closes the lid in case of fire.
6. When servicing small gas engines, accurate measurements must be made to determine whether components are within tolerance limits.
7. Without seeing the actual labeled parts clearly, it's impossible to name them precisely. Common parts of a micrometer include the anvil, spindle, thimble, sleeve, ratchet stop, frame, and locknut.
8. An outside micrometer should be used to measure the outside diameter of a piston or valve stem.
9. To measure the diameter of a cylinder, you should use an inside micrometer.
10. Temperature can affect a micrometer by causing thermal expansion or contraction. If the micrometer is at a different temperature than the part being measured, it can lead to inaccurate measurements. For example, if the micrometer is warmer than the part, it may expand and give a false reading that the part is smaller than it actually is.
11. Before using a micrometer, it should be tested for proper zero - setting.

Answer:

1. Cannot be answered without clear labels.
2. Copper or aluminum jaws/soft - jaw inserts
3. As close as possible
4. Non - flammable
5. Fire - actuated lid - closing device
6. Tolerance limits
7. Cannot be answered without clear labels.
8. Outside
9. Inside
10. Temperature can cause thermal expansion or contraction, leading to inaccurate measurements.
11. Zero - setting
