What is chain surveying?
Chain surveying, also known as linear surveying, is a basic method of land surveying used to measure and map small and relatively flat areas. It is a simple and traditional technique that involves the use of chains or tapes to measure distances and basic instruments to measure angles. Chain surveying is often used for small-scale surveys such as creating maps for agricultural fields, small plots, or subdivisions. Here's how chain surveying works: 1. Measurement of Distances: In chain surveying, distances are measured using chains (typically 66 feet or 100 feet) or steel tapes. These chains or tapes are laid out along the linear features of the land being surveyed, such as property boundaries or roads. The total distance is obtained by chaining together multiple segments. 2. Measurement of Angles: Basic angles can be measured using a compass, theodolite, or other simple instruments. These angles are used to determine the direction of the surveyed lines and to calculate the layout of the land. 3. Stations and Offsets: The surveyed area is divided into smaller segments called "stations." At each station, measurements are taken to locate nearby features or boundaries, and perpendicular lines known as "offsets" are measured to mark points of interest. 4. Plotting: The data collected during the survey is used to create a scaled drawing or map of the surveyed area. The positions of boundaries, features, and angles are plotted on the map to create an accurate representation of the land. Advantages of Chain Surveying: **Simplicity:** Chain surveying is straightforward and requires minimal equipment and training. **Accuracy:** In relatively small and flat areas, chain surveying can provide accurate measurements for basic mapping purposes. **Low Cost:** It is a cost-effective method, making it suitable for smaller projects with limited budgets. Limitations of Chain Surveying: **Limited Coverage:** Chain surveying is not suitable for large or complex areas, as it becomes challenging to maintain accuracy over extended distances or rugged terrains. **Human Errors:** The accuracy of measurements in chain surveying can be affected by human errors, such as miscounting chain links or inaccurate readings. **Lack of Precision:** Chain surveying may not provide the level of precision required for detailed engineering projects or high-precision mapping. In modern surveying, more advanced methods such as total stations, GPS, and aerial surveys have largely replaced chain surveying for larger and more complex projects. However, chain surveying remains a valuable technique for smaller-scale surveys and in situations where advanced technology is not readily available or necessary.
Meaning of water level in civil engineering?
Water level is flat on sea according to civil engineering because water level is same on two point of a flat road. Building top or two point of a wall is flat because water level is same. A top of a building is known as flat if water level is same from all of its side. Water level can be checked by means of two sides of a transparent nylon tube or hose also in civil engineering by putting water inside it as per the length of tube or hose and both the sides had to be raised at the two points where it has to be checked. The level depends on gravitational force on earth from the center of the earth. So surface of road is known as flat. Even table or bed is known as flat. But surface of earth is known as round from outside the gravitational zone of earth from the space, not from earth.From the surface of earth earth is flat because water level is same. From the surface of sea sea is flat because water level of sea level is same. The concept is from sea level as per physics. So it is known for altitude for a location on earth means height above sea level. For example altitude of NEW YORK CITY is 33 feet above sea level.

What is uniformly distributed loads?
Uniformly distributed loads, also known as uniformly distributed loads (UDL), refer to loads that are evenly distributed over a given length or area of a structural element. They exert a constant magnitude per unit length or unit area along the specified region. In the case of one-dimensional structural elements like beams or slabs, a uniformly distributed load applies a constant force or weight per unit length. For example, a beam with a UDL of 10 kN/m means that there is a load of 10 kilonewtons acting on every meter of the beam's length. In two-dimensional elements like plates or surfaces, uniformly distributed loads apply a constant pressure or weight per unit area. For instance, a floor slab with a UDL of 5 kN/m² means that there is a load of 5 kilonewtons per square meter acting on the entire surface area of the slab. Uniformly distributed loads are commonly encountered in various structural applications, such as floor loads in buildings, self-weight of structural elements, dead loads, or evenly distributed loads from equipment or storage. They allow for simplified analysis and design calculations since the load intensity remains constant over the specified area or length. When analyzing or designing structures subjected to uniformly distributed loads, engineers consider the load magnitude, the span or length of the element, and the support conditions. By applying principles of structural mechanics and equilibrium, they can determine the internal forces, moments, deflections, and overall behavior of the structure under the UDL. It's important to note that UDLs are an idealization of real-life loading conditions. In practice, actual loads may vary or have different distributions, requiring engineers to consider more complex load patterns and combinations to accurately analyze and design structures.
What is percentage error?
Given a true value and the measured value,the error is measured value - true value;the relative error is (measured value - true value)/true value, andthe percentage error is 100*relative error.

Why is twenty two yards called a chain?
In 1620, the clergyman Edmund Gunter developed a method of surveying land accurately with low technology equipment, using what became known as Gunter's chain. This was 66 feet (22 yards) long and from the practice of using his chain, the word transferred to the actual measured unit. His chain had 100 links, and the link is used as a subdivision of the chain as a unit of length. A rectangle of land one furlong in length and one chain in width has an area of one acre. It is sometimes suggested that this was a medieval parcel of land capable of being worked by one man and supporting one family, but there is no documentary support for this assertion, and it would in any case have predated Gunter's work.
Until I am measured I am not known Yet how you miss me when I have flown What am I?
Time is not known until it is measured and when it flies it is missed.
What are wave length and wave height?
Wave length, also known as cycle and period, is the difference in magnitude from one point on a wave to the corresponding point on an adjacent wave as measured along, and defined by, the x-axis of the graphed wave forms. Wave height, also known as magnitude, is the distance above or below the x-axis as measured along, and defined by, the y-axis of the graphed wave forms.
How do you calculate measurement uncertainty for acceleration given uncertainty in time?
If the distance is known to perfection, an acceleration is constant, then the absolute error in the calculation of acceleration is 2/t3, where t is the measured time.
What unit of chain length in Britain is equal to 75 feet?
This is one of the dictionary definitions of the word "shot", see http://dictionary.reverso.net/english-definitions/shot. In surveying, the 'chain' means 66ft, 10 chains = 1 furlong, but this is a different use of the unit of chain length. ________________________________________________________________ In the imperial system of measurement there are two units referred to as a "chain". As already stated the usual measurement is the Surveyor's chain (also known as Gunter's chain) = 66 feet. The Engineer's chain = 100 feet. So 75 feet is equal to 1.136 chains, or 0.75 Engineer's chains
