A measuring rod is a tool used to physically measure lengths and survey areas of various sizes. Most measuring rods are round or square sectioned; however, they can also be flat boards. Some have markings at regular intervals. It is likely that the measuring rod was used before the line, chain or steel tapes used in modern measurement. [1]
The width of the reed sets the maximum width of the warp. [4] Common reed sizes for the hand-weaver are 6, 8, 10, 12, or 15 dents per inch, although sizes between 5 and 24 are not uncommon. [9] A reed with a larger number of dents per inch is generally used to weave finer fabric with a larger number of ends per inch. Because it is used to beat ...
One of the most basic forms of frequency meter is the vibrating reed meter or tuned reed meter. This consists of an electromagnet coil carrying the signal positioned near the end of a tuned metal reed or tuning fork-type arrangement. As the signal travels through the coil it creates a magnetic field with the sample frequency, which pushes and ...
Vibrating reed electrometers use a variable capacitor formed between a moving electrode (in the form of a vibrating reed) and a fixed input electrode. As the distance between the two electrodes varies, the capacitance also varies and electric charge is forced in and out of the capacitor.
Surveying and itinerant measurement were undertaken using rods, poles, and knotted cords of rope. A scene in the tomb of Menna in Thebes shows surveyors measuring a plot of land using rope with knots tied at regular intervals. Similar scenes can be found in the tombs of Amenhotep-Sesi, Khaemhat and Djeserkareseneb.

If you want to measure the diameter set the gauges required diameter with master. [clarify] In order to measure the diameter of the bore, place the beam at one end and slide the other end on the diameter and watch the dial indicator. The values initially increases and at one point starts decreasing; stop that point, it is called max point on ...
