Tape measures are often designed for specific uses or trades. Tapes may have different scales, be made of different materials, and be of different lengths depending on the intended use. Tape measures used in tailoring are called "sewing tape". Originally made from flexible cloth or plastic, fiberglass is now the preferred material due to its ...
A measuring instrument for lengths: a typical tape measure with both metric and imperial units and two US pennies for comparison A measuring instrument is a device to measure a physical quantity . In the physical sciences , quality assurance , and engineering , measurement is the activity of obtaining and comparing physical quantities of real ...
Remanence of audio tapes, referred to quarter-inch tape width, varies from around 1100 G for basic ferric tapes to 3500 G for Type IV tapes; [5] advertised remanence of the 1986 JVC Type IV cassette reached 4800 G. [6] Coercivity is a measure of the external magnetic flux required to magnetize the tape, and an indicator of the necessary bias level.
A diameter tape (D-tape) is a measuring tape used to estimate the diameter of a cylinder object, typically the stem of a tree or pipe. A diameter tape has either metric or imperial measurements reduced by the value of π. This means the tape measures the diameter of the object. It is assumed that the cylinder object is a perfect circle.
The wear of an adhesive tape as it slides across a substrate can be estimated using Archard's Law of Adhesive Wear, where and are the hardness and wear coefficients of the adhesive tape, is the distance the adhesive is dragged across the substrate surface, is the total normal load acting on the adhesive tape, and is the volume of the adhesive ...
Inside small jaws: used to measure the internal diameter of an object (like a hollow cylinder or pipe). Depth probe, or depth rod: used to measure depths of an object (like a small beaker) or a hole. Main scale (metric): marked every millimeter and helps to measure length correct up to 1 mm. Main scale (imperial): marked in inches and fractions.
Definition and characteristics [ edit ] One often cited description that Mandelbrot published to describe geometric fractals is "a rough or fragmented geometric shape that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole"; [ 1 ] this is generally helpful but limited.
Standards are used in analytical chemistry. Here, a primary standard is typically a reagent which can be weighed easily, and which is so pure that its weight is truly representative of the number of moles of substance contained. Features of a primary standard include: High purity; Stability (low reactivity)
