What is the step foot?
The step foot is a unit of measurement commonly used in surveying and construction, especially in the United States. It is equal to 12 inches, or one-twelfth of a surveyor's chain.
Why was the clinometer invented?
The clinometer was invented to accurately measure angles of elevation or inclination. It is commonly used in forestry, surveying, and engineering to determine slopes or vertical angles in various applications.
What is an azimuth and elevation?
These are terms used in surveying and astronomy (usually quotes in angles) to denote the apparent position of an object in the sky based on a specific obervation point or an observer on the Earth's surface. See the following link for an example: http://searchcio-midmarket.techtarget.com/sDefinition/0,,sid183_gci838808,00.html
What is a large table with plexiglass used to demonstrate depth perception in small children?
A large table with plexiglass is commonly used as a "visual cliff" to demonstrate depth perception in small children. The table creates a perception of a drop-off on one side, encouraging children to gauge the depth before deciding whether to cross. This is a classic experiment used to study how infants and young children perceive depth and understand the concept of heights.
What is the difference between tablespace and a table?
A tablespace is a logical storage unit that contains segments, like tables and indexes, while a table is the structure within a database that stores data in rows and columns. Tables are stored within a tablespace, which provides the physical storage for the table's data.
Is there any angular measurement in plane table surveying?
no. plane table is used only for measuerment of distances.
What is the function of clamp screw in plane table surveying?
The clamp screw in plane table surveying is used to secure the alidade or sighting equipment in place on the plane table. It helps keep the equipment stable and prevents it from moving while taking measurements or making sightings. This ensures accuracy and precision in the surveying process.
What are general classifications of surveying?
General classifications of surveying include geodetic surveying, plane surveying, topographic surveying, cadastral surveying, construction surveying, and hydrographic surveying. Geodetic surveying deals with large-scale measurements of the earth's surface, while plane surveying focuses on small-scale measurements on a flat surface. Topographic surveying involves mapping of the land's natural features, cadastral surveying deals with land parcel boundaries, construction surveying is used for building projects, and hydrographic surveying is for mapping bodies of water and their features.
What is table assessories?
Table accessories are items used to enhance and complement the appearance and functionality of a table. This can include items like tablecloths, napkins, centerpieces, place mats, and table runners. These accessories are often used to set the mood for a dining experience or event.
What is the differences between radiation and intersection method in plane table surveying?
Radiation is suitable for locating the objects from a single point , while Intersection is suitable for the inaccessible points by intersection of rays drawn from two instrument stations.
When was a plane angle first used?
Plane angles have been used since ancient times, with early civilizations such as the Egyptians and Babylonians using them in astronomy and surveying. The concept of plane angles was further developed by Greek mathematicians, such as Euclid and Archimedes, around the 3rd century BC.
What is the general definition of a light aircraft plane?
A light aircraft plane has a take off weight of no more than 12,500 lbs. This type of plane is typically used for surveying, sightseeing, photography, and personal use. Also used commercially for passenger flights and transporting freight. An example of a light aircraft is the Cessna or Piper.
What are the classes of surveying?
The main classes of surveying are geodetic surveying, topographic surveying, cadastral surveying, construction surveying, and hydrographic surveying. Geodetic surveying deals with large areas and high accuracy measurements for mapping the Earth's surface. Topographic surveying focuses on determining the natural and man-made features of a specific area. Cadastral surveying involves demarcating property boundaries. Construction surveying is done to guide the construction of infrastructure and buildings, while hydrographic surveying is used to map underwater features.
What is chain surveying as used in civil engineering?
chain surveying is one of the types of survey methods. It is used to survey short length lands
Is there a web site that only sells used pool tables and accessories?
There are several options for finding a used pool table online. I would suggest www.billiardsnmore.com
What are ways statistics is used?
Finance. Surveying.
What are theodolites used to measure?
They are surveying instruments used to measure angles.
