Micrometers with a vernier graduation are capable of taking readings to the nearest 0.0001 in. a)- true b)- false

The micrometer with vernier graduation can measure reading to the nearest 0.0001 inches.  So, the statement is true.

Explanation:

Micrometer is the measuring device that used to measure length with more accuracy. Micrometer can measure the length in metric as well as in English unit. Micrometer is generally used to measure diameter and length of the mechanical component.

Working:

Micrometer is a screwed device. It contains spindle, anvil and thimble. Object is placed between spindle and anvil. Thimble is rotated that rotates the spindle till it touches the component completely. Two types of scales are used to measure the reading of micrometer, one is sleeve scale and other is thimble scale. Spindle moves toward component by 0.5 mm in or 0.025 in on every one rotation of spindle. There are three types of micrometer

Least count of micrometer:

Minimum measurement of any measuring device is the least count of that device. So, the least count for normal micrometer is 0.01 mm or 0.001 inches.

The micrometer is called vernier micrometer if the micrometer is provided with the vernier scale. The least count of vernier micrometer scale is 0.0001 inches.

Hence the micrometer with vernier graduation can measure reading to the nearest 0.0001 inches.

Thu, the statement is true.
