Metric Rulers. Making accurate measurements is very important! The first step in measuring the length of an object using a ruler is making sure that you're using the correct ruler. That will depend a bit on what you mean by "ruler". You have to use a mathematic definition of such object. But let's assume that you by a ruler means a line segment accompanied with a scale, that is a linear assignment of "length markings" ranging from 0 up to some maximal value.

A ruler , sometimes called a rule or line gauge , is a device used in geometry and technical drawing , as well as the engineering and construction industries, to measure distances or draw straight lines. Rulers have long been made from different materials and in multiple sizes. Some are wooden. Plastics have also been used since they were invented; they can be molded with length markings instead of being scribed. Metal is used for more durable rulers for use in the workshop; sometimes a metal edge is embedded into a wooden desk ruler to preserve the edge when used for straight-line cutting.
Shorter rulers are convenient for keeping in a pocket. Rigid wooden or plastic yardsticks , 1 yard long, and meter sticks , 1 meter long, are also used. Classically, long measuring rods were used for larger projects, now superseded by tape measure , surveyor's wheel or laser rangefinders. Desk rulers are used for three main purposes: to measure, to aid in drawing straight lines, and as a straight guide for cutting and scoring with a blade. Practical rulers have distance markings along their edges.
A line gauge is a type of ruler used in the printing industry. These may be made from a variety of materials, typically metal or clear plastic. Units of measurement on a basic line gauge usually include inches, agate , picas , and points. More detailed line gauges may contain sample widths of lines, samples of common type in several point sizes , etc. Measuring instruments similar in function to rulers are made portable by folding carpenter's folding rule or retracting into a coil metal tape measure when not in use.
When extended for use, they are straight, like a ruler. The illustrations on this page show a 2 m 6 ft 7 in carpenter's rule, which folds down to a length of 25 cm 10 in to easily fit in a pocket, and a 5 m 16 ft tape, which retracts into a small housing. A flexible length measuring instrument which is not necessarily straight in use is the tailor's fabric tape measure, a length of tape calibrated in inches and centimeters.
It is used to measure around a solid body, e. It is rolled up when not in use, taking up little space. A contraction rule is made having larger divisions than standard measures to allow for shrinkage of a metal casting. They may also be known as a shrinkage or shrink rule. A ruler software program can be used to measure pixels on a computer screen or mobile phone. These programs are also known as screen rulers. In geometry, a ruler without any marks on it a straightedge may be used only for drawing straight lines between points.
A straightedge is also used to help draw accurate graphs and tables. A ruler and compass construction refers to constructions using an unmarked ruler and a compass. It is possible to bisect an angle into two equal parts with a ruler and compass. It can be proved, though, that it is impossible to divide an angle into three equal parts using only a compass and straightedge — the problem of angle trisection.
However, should two marks be allowed on the ruler, the problem becomes solvable. In the history of measurement many distance units have been used which were based on human body parts such as the cubit , hand and foot and these units varied in length by era and location.
The oldest preserved measuring rod is a copper-alloy bar that dates from c. Ancient bricks found throughout the region have dimensions that correspond to these units.
Anton Ullrich invented the folding ruler in Frank Hunt later made the flexible ruler in The equivalent of a ruler for drawing or reproducing a smooth curve, where it takes the form of a rigid template, is known as a French curve. A flexible device that can be bent to the desired shape is known as a flat spline , or in its more modern incarnation a flexible curve.
Historically, a flexible lead rule used by masons that could be bent to the curves of a molding was known as a lesbian rule. Ludwig Wittgenstein famously used rulers as an example in his discussion of language games in the Philosophical Investigations. He pointed out that the standard meter bar in Paris was the criterion against which all other rulers were determined to be one meter long, but that there was no analytical way to demonstrate that the standard meter bar itself was one meter long.
It could only be asserted as one meter as part of a language game. From Wikipedia, the free encyclopedia. An instrument used to measure distances or to draw straight lines. This article is about the measuring device.
