Methods used for the calculation of areas in Surveying

Methods used for the calculation of areas in Surveying: Simpson’s rule Trapezoidal rule Graphical rule Simpson’s Rule Statement It states that, sum of first and last ordinates has to be done. Add twice the sum of remaining odd ordinates and four times the sum of remaining even ordinates. Multiply to this total sum by 1/3 rd of the common distance between the ordinates which gives the required area. Where O 1 , O 2 , O 3 , …. O n are the lengths of the ordinates x = common distance n = number of divisions Note: This rule is applicable only if ordinates are odd, i.e. even number of divisions. If the number of ordinates are even, the area of last division maybe calculated separated and added to the result obtained by applying Simpson’s rule to two remaining ordinates. Even if first or last ordinate happens to be zero, they are not to be omitted from Simpson’s rule. The following offsets are taken from a chain line to an irregular boundary toward...

File attributes and NTFS permissions

Chapter 5 - File attributes and NTFS permissions   We’ve already mentioned both file attributes and NTFS permissions throughout this book. In this chapter we’ll take a closer look at file attributes, and discuss how to view and change attributes from the command line. We’ll also examine NTFS permissions, which are considerably more powerful than file attributes, and discuss how to view and alter them as well.   WHAT ARE FILE ATTRIBUTES?   “File attributes” are basically pieces of metadata that contain additional information about the file. In Windows, files generally have their names, their types (defined by the file’s extension), and their timestamps. (Certain kinds of files, such as MP3 music files, have additional kinds of metadata, such as the album and artist name.) With file attributes, however, there are four additional pieces of information that you can add to a file.  These four pieces of information are: -Archive,...

Construction of lead acid battery

Overview of lead acid battery It is the main overview of lead acid battery,working and construction. In lead acid battery there is a group of cells and in each cell there is one group of positive plates and one group of positive plates and one group of negative plates. The positive plates are made of lead peroxide (PbO2) and negative plate is made of spongy lead. Thus for identification the positive plate as the color of dark brown, whereas the negative plate as the color of light salty, Construction of lead acid battery In this topic we are discussing about the lead acid battery working , and construction . mainly construction you can watch the video  Main parts of lead acid battery 1. Separator. It is most important part of lead acid battery. Which separate the positive and negative plates from each other and prevents the short circuit? The separators must be porous so that the electrolyte may circulate between the plates . The separators must have...
