Triangulation. … Triangulation is a
surveying method that measures the angles in a triangle formed by three survey control points
. Using trigonometry and the measured length of just one side, the other distances in the triangle are calculated.
What is triangular method?
[trī′aŋ·gyə·lər ′meth·əd] (mining engineering)
A method of ore reserve estimation based on the assumption that a linear relationship exists between the grade difference and the distance between all drill holes
.
How do you do triangulation in surveying?
In surveying, triangulation is the
process of determining the location of a point by measuring only angles to it from known points at
either end of a fixed baseline, rather than measuring distances to the point directly as in trilateration.
What is the importance of triangulation in surveying?
Applications of Triangulation Surveying
Establishing accurately located control points for plane and geodetic surveys of large areas
. Accurate location of engineering projects such as Centre lines, terminal points and shafts for long tunnels, and Centre lines and abutments for long span bridges.
What is the principle of triangulation?
The principal of triangulation is as follows: i)
If we know one side and two angles (three angles) of a triangle then the remaining sides can be determined
. ii) If we know direction of one side then the direction of remaining sides can be make up accurately.
What is triangulation structure?
Triangulation is
the engineering practice of forming rigid triangles together with adequate fasteners at the joints
. It typically involves the use of triangular shapes to give stability to structures.
Where do we usually use triangulation method?
Abstract. Triangulation is a technique to
analyze results of the same study using different methods of data collection
. It is used for three main purposes: to enhance validity, to create a more in-depth picture of a research problem, and to interrogate different ways of understanding a research problem.
What is triangulation and why is it important?
Triangulation
facilitates validation of data through cross verification from more than two sources
. It tests the consistency of findings obtained through different instruments and increases the chance to control, or at least assess, some of the threats or multiple causes influencing our results.
What are the four types of triangulation?
In 1978, Norman Denzin identified four basic types of triangulation:
(1) data triangulation: the use of multiple data sources in a single study
; (2) investigator triangulation: the use of multiple investigators/research- ers to study a particular phenomenon; (3) theory triangulation: the use of multiple perspectives to …
Why is it called triangulation method?
Triangulation is an analysis technique used in multi-method research designs. … Triangulation is a term that was borrowed from surveying, where it refers
to the collection of different compass bearings (usually three, hence triangulation)
in order to pinpoint a location on a map.
What is triangulation in mechanical engineering?
triangulation, in navigation, surveying, and civil engineering,
a technique for precise determination of a ship’s or aircraft’s position, and the direction of roads, tunnels, or other structures under construction
.
What does triangulation mean in design and technology?
According to the Encyclopedia of Research Design: Definition: Triangulation is
the practice of using multiple sources of data or multiple approaches to analyzing data
, to enhance the credibility of a research study.
What is triangulation and why is this used in pylons?
If you look at some pictures of familiar frame structures like cranes, electricity pylons or roof supports you may notice that
triangulation is used to make them rigid
. By adding an extra bar or member, the structure then cannot be forced out of shape, and is said to be rigid. … This is known as triangulation.
What is the most common type of triangulation?
Data Triangulation Data triangulation
involves using different sources of information in order to increase the validity of a study. This type of triangulation, where the researchers use different sources, is perhaps the most popular because it is the easiest to implement.
What is triangulation method Class 11?
Triangulation is
the process of determining the location of a point by measuring the angles to it from two known points
rather than measuring distances directly.
Why does triangulation need 3 points?
With two signals, the precise position could be any of the two points where the circles intersect. Because we have a third satellite,
it reveals your true location where all three circles intersect
. Using three distances, trilateration can pinpoint a precise location.
What technique is used to strengthen electricity pylons?
Frame structures can be made stronger by using
struts
. A strut is a solid bar joined into a structure to make it more stable. Struts are used in roof trusses, bridges, cranes and pylons. Skeletons are frame structures made of a system of struts.
Who discovered triangulation?
The idea of triangulation was apparently conceived by the Danish astronomer Tycho Brahe before the end of the 16th century, but it was developed as a science by a contemporary Dutch mathematician,
Willebrord van Roijen Snell
.
What structure is a pylon?
A pylon is
a large vertical steel tower-like structure
that supports high-tension electrical cables. Because power lines are typically 400,000 volts, and ground is at an electrical potential voltage of zero volts, pylons create electric fields between the cables they carry and the ground.
What purpose do pylons serve?
pylon, (Greek: “gateway”), in modern construction,
any tower that gives support
, such as the steel towers between which electrical wires are strung, the piers of a bridge, or the columns from which girders are hung in certain types of structural work.
What is family triangulation?
Triangulation means that
a third person either within the family or someone from outside
, is brought in and selected as a way to protect the integrity of the family by ending any perceived threat to the system.
In trigonometry and geometry, triangulation is
the process of determining the location of a point by forming triangles to the point from known points
.
What is triangulation in quantitative research?
The term triangulation refers to
the practice of using multiple sources of data or multiple approaches to analyzing data to enhance the credibility of a research study
. … First, data triangulation involves using multiple sources of data in an investigation.
