GENERAL PRINCIPALE OF SURVEYING

The general principal of surveying are; to work from the whole to the part and, to locate a new station by at least two measurement, line or angular from fixed reference points. Technical Data used in the field explained in civil surveyor course in Rawalpindi. According to the first principle, the whole area is first enclosed by main stations, I.e., controlling stations, and main survey lines ,i.e. controlling lines.

 The area is then divided into a number of parts by forming well-conditioned triangles. A nearly equilateral triangle is considered to be the best well-conditioned triangles the main survey lines are measured very accurately with a standard chain. Then the sides of there triangles are measured. Some more details of civil surveyor course in Rawalpindi are as under.

The purpose of this process of working is to prevent accumulation of error. During this procedure, if will not affect the whole work. The error can always be detected and eliminated. But if the reverse process, i.e. form the part to the whole, is followed, then the minor errors in measurement will be magnified in the process of expansion and a stage will come when these errors will become absolutely uncontrollable. According to the second principal, the new station should always be fixed by at least two measurements, line or triangle, from fixed reference points.

Introduction to Pillow Block Bearings and Roller Bearings

Pillow block bearing is the type of bearing found inside a cast iron bracket, which also serves as the bearing's outer housing. Technical Data used in the field explained in civil surveyor course in Rawalpindi, This is usually made from gray cast iron, and has the provision to let the housing be securely bolted down. The material of its inner bearing component is generally made from soft metal, like white metal, whereas its outer housing can either be a single or split housing. Though this bearing is principally designed for situations that involve minimal loads and low torque, it can also be used in industrial settings with clean environments.

The term pillow block bearing is frequently exchanged for Plummer block bearing in some countries, but these are not one and the same device. The Plummer block has no inner bearing, unlike a pillow block bearing. Furthermore, it is designed for corrosive, industrial settings and higher load situations. However, there is one feature common to these two bearing housings. Both can be bolted to stable surfaces by means of using cast-in bolt mounting holes located on the body assembly's base.

The roller bearing, which is spherical or cylindrical in shape, helps in moving things, particularly large, heavy ones. Its main function is to lessen the resistance and friction experienced while moving objects. Roller bearings are frequently seen in machines or industrial products, such as conveyor belts. They allow a smooth and easier transport of objects by effectively distributing their weight. It is typical for a bearing to have several points of contact, since its circular housing has rolling elements inside it, like ball bearings inside a collar.

Roller bearing systems come is a range of types and designs, making them useful in industrial applications and machines. A cylindrical roller bearing contains a metal collar, which has an inner small, toothed wheel. The wheel has teeth that securely hold the ball bearings inside the wheel. When the load is being moved, the wheel turns around, but the load's weight stays fixed above the spherical ball bearings within the cylinder.

What Is An Automatic Level?

The automatic level is one of technology's more recent versions of the construction level. Technical Data used in the field explained in civil surveyor course in Rawalpindi, How is the automatic level different from earlier versions of construction levels such as the wye and dumpy level? In order to understand what an automatic level is, we must first know a little about construction levels in general.

Construction levels can be compared to carpenter's levels. Carpenter's levels are used to determine if two points a few inches apart have equal elevation or are horizontal. Like the carpenter's level the construction level incorporates the spirit level, which is the little slightly curved glass vial filled with a colored spirit. In this case the spirit is alcohol with a bubble floating in it. But in order to transfer a horizontal line a distance to another point, construction levels were developed with the spirit vial attached to a telescope. The telescope is mounted on a vertical axis, about which it can swing horizontally and is adjusted by four leveling screws. All of this makes up the instrument which is mounted on a tripod to stabilize it and to bring it up to the operator's eye. Some more details of civil surveyor course in Rawalpindi are as under.

Examples of earlier versions of the construction level that utilized the spirit vial are the wye level, also written "Y level"; the dumpy level; and the tilting dumpy level. The wye has the spirit vial attached to the telescope. The telescope rests on a horizontal bar that is rigidly attached to the vertical axis and adjusted by three to four leveling screws. The wye is unique in that the telescope can be unclamped and removed from the horizontal bar, turned end for end, and replaced. This is done when testing the bubble for adjustment. The wye is generally no longer available as a new instrument.

Failure to Define Technical Terms

Failure to explain/define professional, trade and technical terms. Technical Data used in the field explained in civil surveyor course in Rawalpindi.You know the meanings of the technical/professional terms and phrases you use when you write about the subject of your book. But, though dense with meaning to you, these words may not be as meaningful to lay readers. For example, in a golf book, terms beginners may not be familiar with like "slice," "hook," "follow through," etc.

Or in a book on recovering from sex addiction, words and phrases like "inner child," "codependent," even "recovery" itself, may be new to those just beginning their quest for healing. When should you define a word or phrase, and when can you assume everyone will be familiar with them? A good rule is to define every technical, professional or academic word you use. If any turn out to be unnecessary, your editor can delete them from the final text. Some more details of civil surveyor course in Rawalpindi are as under.

Hint: Error on the side of safety and define, define, define. Another serious reader turn-off is describing something in terms of what it "is not." When you put it that way, it seems silly. The very definition of "description" is a summarizing of what something "is." Yet, far too often, writers fall into exactly that trap. I once edited a manuscript on meditation whose author devoted the first chapter to explaining what meditation was not. Unfortunately, the author neglected to explain what meditation was. When this failing was pointed out, she immediately revised the chapter and devoted the majority of the space to detailing what meditation is. without relying solely on negative comparisons.
