Answer to Question #210394 in Physics for Phumzile Zondi

Question

Explain the method by which a micrometer is used to determine the depth or the size of an object

Answer 1

For measurement using an outside micrometer, an object is placed flush against a micrometer caliper's anvil. The thimble is turned with the other hand, moving the spindle closer to the anvil until it can move no further. When the object is secure between the anvil and spindle, the micrometer is locked so that a measurement can be read and recorded accurately. A standard, one-inch micrometer has readout markings of .001 inch with an accuracy of +/- .0001 inch.
