Introduction
A ruler is a common measuring tool that is used to measure lengths, depths, and heights. A ruler is graduated into uniform increments and is either made of a material like glass or metal or can be printed onto paper, such as in a school practice book. In a mechanical setting, rulers are used to measure accurately and precisely in order to construct and repair items.
Types of Rulers
There are a few different types of rulers that are used in a mechanical setting. These rulers include a standard ruler, a divider, a beam, a micrometer, a caliper, and a dial indicator. Each of these rulers has their own specific purpose in a mechanical setting.
Standard Ruler
The standard ruler is probably the most common measuring tool used in a mechanical setting. Standard rulers are typically straight and have uniform increments all along their length. Standard rulers are made of metal, plastic, or glass and are capable of measuring lengths up to a foot or more.
Divider
Divider rulers are also used to measure lengths, but they have two pointed arms that are used to mark and transfer measurements more accurately. Divider rulers are made of metal and are more precise than standard rulers.
Beam
Beam rulers are used for measuring large lengths, such as in construction and carpentry. These rulers are made of a straight piece of metal or wood with uniform increments.
Micrometer
The micrometer is a small, hand-held ruler that is used to measure small distances accurately. It is composed of a screw and a thimble which is rotated to measure increments in small increments.
Caliper
Caliper rulers are used to measure the exterior diameter or interior diameter of an object. They are composed of two arms that are adjustable, so they can be used to measure different sizes.
Dial Indicator
Dial indicators are used to measure small increments accurately. They are composed of a dial that has a needle that is moved to the desired measurement. Since they are a dial, they can measure accurately in small increments.
Uses of Ruler
Rulers are used in a mechanical setting to accurately measure lengths, depths, and heights of various materials. In carpentry, rulers are used to measure the length and width of a piece of wood. In engineering, rulers are used to measure the length, width, and height of a part in order to build a prototype or a machine. In electrical engineering, rulers are used to measure the length of a wire or other electrical component.
In a machine shop, rulers are used to measure the size of a hole. This is necessary when creating a part or repairing a part. The ruler can be used to measure the size of a hole to ensure it is either the correct size to meet the specifications of a part or that it meets the industry standard.
Conclusion
Rulers are a common measuring tool that are used in a mechanical setting for measuring lengths, depths, and heights. There are a few different types of rulers that are used in a mechanical setting, including standard rulers, dividers, beams, micrometers, calipers, and dial indicators. Rulers are used to accurately measure parts in a machine shop and to measure the length and width of materials in carpentry and engineering projects.
