Advantages of 3-point micrometer: improved accuracy and reduced measurement error due to additional contact points, suitable for measuring non-round parts. Disadvantages: more complicated setup and calibration, higher cost compared to 2-point micrometers.

Advantages of 2-point micrometer: simpler setup and operation, lower cost compared to 3-point micrometers. Disadvantages: may have decreased accuracy and increased measurement error compared to 3-point micrometers, limited suitability for measuring non-round parts.

What is the total movement indicated on the thimble if it has been rotated one revolution on a micrometer from zero?

It depends on the screw thread pitch (or "lead") in the heart of the micrometer. Typically, screw pitches in common hand-held micrometers are 40 per inch in an Imperial micrometer or 2 per millimetre in a Metric micrometer. Thus, one full turn of the thimble of an Imperial micrometer is 1/40th of an inch (25 thousandths of an inch or "25 thou") and similarly, one full turn of the thimble of a Metric micrometer is 1/2 a millimetre (500 micrometres).


What is the accuracy of micrometer screw gauge?

The accuracy of a micrometer screw gauge is typically around 0.01 mm or 0.001 mm, depending on the precision of the instrument. This means that it can measure lengths with a high degree of accuracy within these limits.


Which of the following can be called non-conventional source of energy?

The non-conventional sources of energy are: 1. Wind Energy advantages- non-polluting; low cost production of electricity once setup; safe and clean disadvantages- noise pollution; wind mills costly to setup; disturbs radio and T.V. reception; harmful to birds. 2. Solar Energy advantages- inexhaustible; non-polluting disadvantages- expensive; diffused source, so gets wasted. 3. Tidal Energy advantages- non-polluting; inexhaustible disadvantages- destroys wildlife habitat; difficult to harness 4. Nuclear energy advantages- Emits large amount of energy disadvantages- generates radioactive waste; expensive 5. Bio Gas advantages- low cost; easy to operate; makes use of bio waste disadvantages- causes green house effect 6. Geothermal Energy advantages- clean Eco friendly and always available disadvantages- located far away from cities and so costly to transport the electricity


What is a range of micrometer?

Metric micrometers are designed to 25mm range portions. They will be supplied in 0 to 25mm, 25 to 50mm, 50 to 75mm, etc. Tube or three-point micrometers come in smaller ranges though. Imperial micrometers come in 0 to 1in, 1 to 2in, 2 to 3in, etc.
