What is the significance of force polygon?

a polygonal figure, the sides of which, taken successively, represent, in length and direction, several forces acting simultaneously upon one point, so that the side necessary to complete the figure represents the resultant of those forces.

What is force polygon and funicular polygon?

a graphical method of finding the reactive forces and resultants of a system of forces, constructing bending-moment diagrams, determining the rational shapes of arched and suspended systems, and solving other problems of the statics of two-dimensional systems.

What is polygon method?

The polygon method is a method for finding sum or resultant of more than two vectors. (Can be used for two vectors also).

What is the Thiessen polygon method?

The Thiessen polygon (Figure T5) is a commonly used methodlogy for computing the mean areal precipitation for a catchment from raingauge observations which was presented by A.H. Thiessen (1911). The area of each polygon is used to weight the rainfall amount of the station in the center of the polygon.

Which figure is a polygon?

A polygon is any 2-dimensional shape formed with straight lines. Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons. The name tells you how many sides the shape has. For example, a triangle has three sides, and a quadrilateral has four sides.

How many forces are acting in Polygon law of forces?

Polygon law of forces. It states, “If two forces acting simultaneously on a particle, be represented in magnitude and direction by the two sides of a triangle, taken in order; their resultant may be represented in magnitude and direction by the third side of the triangle, taken in opposite order.”

Why Isohyetal method is more accurate?

Answer: The isohyetal method is considered to be more accurate than the Thiessen polygon method or gridpoint technique to estimate rainfall totals because it includes the effects of local features.

What is the difference between the voronoi and Thiessen polygons?

Voronoi diagrams that are used in geophysics and meteorology to analyse spatially distributed data (such as rainfall measurements) are called Thiessen polygons after American meteorologist Alfred H. Thiessen.

What is polygon formula?

Polygon Formula The important polygon formulas are: The sum of interior angles of a polygon with “n” sides =180°(n-2) Number of diagonals of a “n-sided” polygon = [n(n-3)]/2. The measure of interior angles of a regular n-sided polygon = [(n-2)180°]/n. The measure of exterior angles of a regular n-sided polygon = 360°/n.

What is the polygon method?

In polygon method of finding the sum or resultant of vectors →P,→Q, The resultant vector →R is drawn from the tail of first vector to head of the last vector. it may so happen that head of the last may end at the tail of first vector, resulting in a closed polygon. In such a case →R=0 or it is called null vector.
