What is a micrometer?
micrometer screw is a hand device used to measure very small lengths and thickness. Examples of its measurements include a tube width or wire thickness. The micrometer screws come in at least three different design variations, but all use a finely calibrated screw for precise measurements. The micrometer screw can be calibrated to occupy several different types of measurements, which makes them useful in several different disciplines.
Most micrometers screws have four important parts: a handle, a calibrated screw, a frame and an anvil. The frame holds the anvil at a distance from the screw. When the bolt is twisted, it reduces or increases the distance between the end of the screw and the anvil, similar to the defect. Some micrometer screws simply have a handle and bolt connected. It is held against an object to be measured similarly to a ruler. The reading is the same along the entire length of the screw. In this way, when the screw is twisted, it can provide accurate measurement. The screw base will be marked with zo linesBrazing each measuring unit. When the user is associated with those who are on the micrometer handles, the user can see the measurements made.
micrometer screw may have different side dishes that can be switched on and off to measure different objects. They also come in various designs to facilitate measuring different types of objects and distances. Individuals can buy a micrometer screw, which specifically measures widths, slots and holes. The screw can also measure depths, diameters and pipe thicknesses. They are available in metric and American measurement systems.
The French astronomer named William Gascoigne is attributed to the creation of the first work micrometer in the 16th century, although the termination existed earlier. He used it to measure the distances between the stars, as seen by his telescope.
Before that, the distance between the sun and the horizon to navigate the navigation was used sextant. WasOnly measuring the mere eye and Gascoigne realized that the screw can be done much more accurate measurements. With these measurements he was then able to make calculations related to the size of planets and stars he saw in the sky. The accuracy of the micrometer in time led to its development for measuring earthly buildings. They began to be widely produced in the 18th century.
